Some thoughts on poetry

Neolithic bone flute, China (Wiki)

I thought it was long overdue time that I wrote something on poetry – my historical fiction books lean heavily on poetry, and my various science fiction and fantasy books are regularly built around music and singing – something I reckon will forever be a part of human experience, wherever we end up living. Music has transformed itself many times over since our prehistoric forebears first accompanied their own voices on wind, string or percussion instruments. We have listened to and participated in music played solo or in groups, small and large.

The Muses (greekmythology.com)

But today I am writing about poetry, not music, though the two are very closely related – probably the topic of another blog sometime. Six of the nine Greek muses were explicitly involved with music and poetry, and the focus of the other three was on pursuits which depended heavily on them. In the myths, the muses were not just engaged in fun and celebration – they also turn up to defend their reputation and avenge themselves on mortals who presume to challenge their primacy.

When most people in the modern world think of poetry, we typically imagine lines of regular beats with some sort of rhyme scheme – either adjacent lines rhyming in an AA-BB pattern, or alternating lines sounding like AB-AB, or the looser version AB-CB. For example, the American anthem, The Star-Spangled Banner, uses ABAB for the first four lines of each stanza, and AA-BB for the last four. At the casual end of the scale, Mary had a Little Lamb uses AB-CB. We all know that “real” poetry does not always adhere to these basic patterns, but if asked to come up with a rhyme on the spur of the moment, these basic schemes will probably come to mind.

Musicians from ancient Egypt (British Museum – Wiki)

Most of the earliest poetry that we have, however, is not built around rhyme, nor indeed around a regular pulse or metre. Instead, early poetry from Mesopotamia and Egypt, followed later all around the ancient near east and so also appearing in the Hebrew Bible, was built around the idea of parallelism. (Ages ago I wrote a post about how this pattern also turns up in the much more recent Finnish epic Kalevala) Pairs of lines expressed the same idea in different ways, without special regard for the exact number of syllables or metrical beats, or any rhyming pattern. Something like the start of the Ugaritic epic poem of king Keret:

The clan of Keret died out;
the house of the king was destroyed

Now the advantage of parallelism, from the point of view of other people trying to understand it, is that it is comparatively easy to translate. There will almost certainly be subtleties of the language, word plays and the like, which don’t translate, but the basics certainly do. But poets rapidly wanted to make their work richer and more complex. So variations of parallelism arose – words omitted or added in the basic couplets, changes of word order to invert the second line, triplet forms extending the basic pairs, and so on. The parallelism of words was enhanced by using alliteration of consonants to reinforce the connecting sounds.

So the stage was set for end-rhyme to make its appearance in poetry – the pattern that we are most used to today. You can look at end-rhyme as just another form of parallelism – but instead of the line endings being signalled by words with parallel meaning, something opposite is happening. The correspondence of rhyming words at the line ends makes us put them in parallel, and so establishes links between words which otherwise would remain separate in our minds. The more appropriately creative the rhyme, the more striking becomes the connection between words in our minds. William Blake’s Tyger has the following lines, provoking us to make connections between spears and tears

When the stars threw down their spears
And water’d heaven with their tears

And again, poets play with our expectations of rhyme in order to jolt us into a different interpretation. Sometimes called a “censored rhyme”, it is often used to suggest politically subversive or sexually risque themes – the actual words themselves are typically innocent, but the expectation aroused in the listener is not. My favourite example is Sweet Violets… almost every line sets the listener up to expect a particular rhyming word, and then diverges away…

There once was a farmer who took a young miss
In back of the barn where he gave her a lecture
On horses and chickens and eggs
And told her that she had such beautiful manners

That suited a girl of her charms
A girl that he wanted to take in his
Washing and ironing and then if she did
They could get married and raise lots of

Sweet violets
Sweeter than all the roses…

An authorised version of these songs (cover image – Caedmon Songs – see https://www.discogs.com/release/1039597)

This all has a lot to do with writing. Some authors want to include real poems in their books, as opposed to saying something along the lines of “then they sang a song”. So then you have to decide how your poem is to be structured in a formal sense, and whether you want that to mirror the conventions of the time of the setting. So a book set in the ancient near east – if it is to be authentic to its era – would not use rhyming couplets, but parallel ones. A story set in Anglo-Saxon times would use the conventions of Germanic poetry, built heavily around word alliteration and stock verbal images with little if any rhyme. A fantasy or science fiction book is free to build up its own conventions as to how poetry in that world is created – but would be enriched by making those fictional conventions fully integrated into the wider world-building . It’s a habit of thought that Tolkien was a master at – he had the advantage of being able to draw on a wide variety of early conventions of song and poetry, and he deployed these conventions so carefully that you can tell almost at first read of one of his poems, which of the various peoples of Middle Earth are in focus (see the Open Culture web site for some readings)

To close, here’s a video of ancient Irish music, found at http://www.ancientmusicireland.com. A wealth of information and live demonstrations, with (to my ears) odd resonances in the music of Bladerunner

Living on Someone else’s land

The finished item…

Many of you know that last week I was heavily involved in getting some refurbishment work done to a bar in Grasmere, Cumbria. It really did get finished on time, albeit needing a couple of long days and late nights. But I’m not going to blog about that. Nor – though I did consider it – an I going to blog about how pretty much every project pushes the envelope on its expected finishing time (even Gandalf apparently suffered from this, judging by his complaint in the film version of Lord of the Rings, “Three hundred lives of men I have walked this earth and now I have no time”).

One of the jackdaws…

Instead, I’m going to talk about something that occupied my mind during several journeys from the bar back to our storage area in some former barns late at night. It is pretty dark in that part of Grasmere, and I didn’t bother with a torch or anything until I was actually poking around trying to find some small-but-essential gizmo to take back. And as I walked down the cul de sac which is Lake View Drive, across the lawn, and down the rough track to the barns, with empty fields on one side going down to the lake, the night was alive with all kinds of animal and bird noises. Of course we have herons and jackdaws as regular visitors – uninvited, but normally welcome – along with a bunch of regular garden birds. Buzzards drift overhead every so often. At this time of year the lake shore is full of geese, swelling the regular swan and duck population. And so on. These are all familiar.

Three badgers playing…

But as well as these, there are the nocturnal creatures that we share the land with, but don’t interact with very much. I’ve mentioned the badgers before, and right now we often get what look to me to be a group of juveniles playing – this night-camera picture shows them beside one of the apple trees, complete with protective fence. A few minutes later they all headed off in a group towards the barns. Maybe they wanted to sample the batch of lager we had just started off?

Why protect the apple trees? Well, that has to do with another of our nocturnal visitors – a small herd of deer. These are very much less welcome. On the night camera I have seen up to half a dozen at a time, led by a rather splendid looking stag. They have been steadily decimating a row of laurel bushes, which we don’t mind so much as they will bounce back, but also various bulbs and small plants which we want for the spring. According to local rumour, several of the local farmers are suffering rather more serious commercial loss from this little bunch.

One of the deer…

Anyway, all this set me thinking that we are only one of the occupants of this piece of the British landscape, and that deer, badgers, rabbits, herons and whatnot have in all likelihood been wandering around the area much longer than we humans have. And this has been true for most of human history. As we spread out, ages ago, from Africa and the Near East, we were perpetually coming into contact with the existing occupants of land which, to us, was unknown. We met predators and prey, and reacted accordingly. We met other hominids – Neanderthals , Denisovans, and others. Sometimes we settled peacefully and mated with them, other times we met in war. But until very recently, we knew that the land we moved across and settled in was not really our own – we were simply a recent arrival, joining others who had lived there for many years already. A lot of that sense of shared occupancy seems to me to have evaporated. We frequently assume these days that we are the sole – or at least the single most important – residents in any particular patch of the planet. That’s a big subject, and one for another day.

Turning now to writing, most novels set in the past should have this as part of the background. Different cultures at different times might express that idea differently – birds and beasts , angels and demons, selkies and spirits – but it should always be there. And it’s kind of regular stock in trade for fantasy literature.

But, as usually happens, this propelled my thoughts forward into science fiction. How can this sense of shared living be captured in that medium? As and when we move out from this planet into the other worlds of the solar system, and potentially beyond, will we recover that sense of having to share the environment with others? This might, of course, be in the most overt and incontrovertible way – an unequivocal meeting with intelligent aliens. But it might also be something much less obvious, such as microbes living in the sub-surface oceans of some of the larger moons circling the outer planets – Titan, Europa and Enceladus for sure, Ganymede and Callisto possibly. Or maybe forms of bacterial life in underground salty lakes on Mars. Or some manifestation of life that as yet we don’t know how to recognise.

How will it be, I wonder, to recover an everyday sense that we are shared occupants of the universe, not solitary ones?

Preparing to build

A couple of weeks ago I blogged about aluminium smelting. Today’s topic is a little more prosaic, but historically has been a much more frequent part of building projects.

The various bits of wood – house beams in front, oak timbers behind

One part of remodelling the bar at The Good Sport is to replace the bar worktop. The old one was a hybrid affair with some chipboard and some stone – the new one is made of wood taken from various sources. There are former house timbers dating from some time in the mid 19th century. They’re very cool, not least for the history they have witnessed. Then there are frame support pieces made just from builders’ merchants supplies, probably pine or something similarly quick growing. But the best sections are two large pieces of oak, rescued by a local craftsman when the tree was felled. These are cut top to bottom along the trunk, so you cannot count the rings and find out how old they are – but my guess is that they considerably outdate the rest of the installation. (The top-to-bottom orientation means that the grain runs along the counter top).

But the thing I want to talk about today is not the age of the wood, but the preparation that has gone into it. The two pieces had been supplied to us reasonably smooth – but “reasonably smooth” menas “not smooth enough” when it’s a thing that people will be leaning on. So one of my jobs these last few days has been to turn “reasonably smooth” into “really smooth”.

One of the pieces of wood, together with the belt sander

Now, since this is 2019, I used a selection of power tools to effect this change, mostly a belt sander with a number of different grades of sandpaper. Even with that, it took a decent time to go over the top surface multiple times, working from coarser to finer passes. I was extremely happy with the result, but it also led me to consider how things might have been in the many ages of our world before power tools were invented. After all, sanding wood is an activity which lends itself to thinking about other things while you’re working away. How long, I mused, would this have taken me if I was doing it all by hand? And would the final result have been anything like so pleasing? After all, wood-smoothing is not something that I have done much of in my life to date, and I wouldn’t call myself especially skilled at it.

Swimming reindeer, c.13,000 years old (BBC)

Human history is full of exquisitely crafted objects, meeting needs somewhere between religion, art, and practical necessity. This swimming reindeer figure was made around 13,000 years ago – I don’t know how long it took the original artist to fashion it, but I’m guessing that it was rather longer than the time I put into smoothing two essentially flat pieces of wood. Not to mention the huge number of practice hours he or she had put in since childhood.

Now, I only smoothed one side of the wood – the pragmatic nature of today’s world means that I wasn’t motivated to do much to the hidden side except to make sure it was proof against various kinds of wood pests. But back in the day, if the kings or the priests felt it important to take just as much care on the hidden side as the visible one, then you would just have got on with it.

Which brings me to the future. There’s a developmental principle in some games – those in which the time frame of the game is spread out over many years – that items which are available only to the wealthy in one era get diffused more and more widely through the population as a whole as you go forward in time. I guess the standard example is computing power – back in the 1950s and 60s, computers could only be owned by large institutions or extremely wealthy individuals. Now we all have much more powerful machines we carry around in our pockets. Similarly for smooth bits of wood – once upon a time it took real skill and craft to create something smooth and shapely from a rough-hewn piece of timber. Nowadays anyone who wants can go out and buy power tools and achieve something similar by themselves (not necessarily with artistic flair, but certainly with polish).

The world’s first 3d-printed house (BBC – https://www.bbc.co.uk/news/technology-44709534)

Now, as and when we get to build colonies and habitats in various places around the solar system, my bet is that we will use 3d printing as our construction technique. After all, it’s way simpler and cheaper to ship out a large printer to wherever you’re going, and use that to construct tools, equipment, and habitat sections – much cheaper than paying for the fuel to send actual construction materials. That’s very cool, but unless the technology advances in aesthetic ways as well as practical ones, I can’t see 3d-printed building materials having a wood grain that can be sanded and then picked out with oil. On one level it doesn’t really matter – you’d prefer that your house on, say, the asteroid Ceres was airtight and warm, even if that meant not having a wood grain to look at. Or maybe we’ll have a printer add-on that will simulate the grain in whatever direction you want.

After preparation…

Metal Working

Civilisation Box Art (Wiki)

Since I first discovered it – many years ago – I have loved the game of Civilisation. I was introduced to version 1 of the computer game by a work colleague, and since then have played various variants of both the computer and the board game. Of course there are all kinds of opinions about which is best, which I don’t propose to go into. But one of the key features was the technology tree – the very very long series of inventions and ideas you pursued in order to build new stuff and so develop your culture.

Now, one of the very early developments was Bronze Working (which allowed specific kinds of military units and civic wonders). This was a prerequisite for Iron Working and – after a very long time – Metallurgy.

The smelting fire

So, what has this to do with today’s blog? Well, yesterday, as a small part of a sizeable remodel of The Good Sport bar, we had cause to do some invention ourselves. We weren’t working with Bronze or Iron, but rather Aluminium. Now, a purist will perhaps object that Aluminium is not on the Civ tech tree – at least, not any of the variants I have played – which is true. And also that we were not starting from bauxite or any other naturally occurring raw material, but rather from some handy spare aluminium sheets that were lying around. All that is true: nevertheless we did have to melt said stuff and refashion it for our own purposes.

Now, aluminium melts at just over 660° C, which is well above the temperature of a domestic oven, or camp fire. So our solution was an old beer keg, lined with cement to retain heat and equipped with an air inlet to one side. Inside was a charcoal fire, and a handy air compressor pushed air in through the tube to keep the charcoal burning fiercely. Aluminium was cut into small strips and put in a steel jug – steel having a much higher melting point. And then we waited, entirely unsure whether the whole thing was doomed to failure.

But as you can see, it all worked! Slowly but surely the aluminium melted into the rather fine puddle that you see in this picture. It would be nice to say that we had been totally confident in all this, but not so – we were as amazed as anyone when this happened. We felt, just for a few moments, like real discoverers. Yes, all the technical data about melting points is easy to obtain these days, and yes we had those handy aluminium sheets as starting point, but even so the sense of triumph when it turned into liquid was extraordinary!

Pouring the liquid aluminium

So what did we do with our liquid aluminium? Well, here it is being poured into a surface hole in a piece of wood. Why that destination? Well, that will all become clear – hopefully – over the next few weeks.

Meanwhile, this all set me thinking about metallurgy in general, and how it has affected human society. Of course Civilisation focuses on just a few things – military units that can now be built, particular buildings that facilitate further development, and “wonders” which enhance your prowess (ie score) and make your people happier. But in reality, metal working permeates every aspect of life.

We take it for granted now that a household object is made of whatever material is most suitable – metal, ceramic, fabric or whatever. We have whole fields of study concerning the various properties of these materials, such as their hardness, ability to transmit or suppress noise, colour, safety, electrical conductivity, and so on. But starting way back in the mists of time, and carrying on through all of our history until now, people have had to find these things out by trial and error. What were the properties of those shiny veins in rock layers? Why could I shape one metal easily and not another? Would my camp fire soften them? How must I change my camp fire so I can work with the more intransigent metals? How can my sword edge be sharper, or my armour tougher, or the wheels on my vehicle stronger? In a very small way, we felt something of the same exhilaration that our hugely distant ancestors must have felt, seeing copper melt for the first time, and be shaped into something new – something distinctly human.

Spacehounds of IPC cover (Wiki)

Looking ahead into the future, we generally assume that we will carry the ability to fashion metals (and other useful substances) with us wherever we go. But every so often you get stories where someone is stranded and has to build it up again. This was an especially popular theme in the 1930s and thereabouts – Spacehounds of IPC being a classic example. Our Hero, forced by circumstance onto an uninhabited moon (with breathable atmosphere) has to start from next to nothing except a small tool pack, and build his way up through small camp fires to blast furnaces and ultimately the ability to recharge the power banks on his derelict lifeboat. Until yesterday, I was totally sceptical about this storyline… but having turned an old keg, some charcoal, and a handy air compressor into something that could melt aluminium, I became slightly more convinced!

More of this another time: for now here is a final picture of the “forge” as it died down in the late evening. You can easily imagine us around it, feeling foolishly triumphant…

Fermentation

Last week’s blog post, all about alcohol and law, triggered a number of interesting discussions, and one of them (from a Goodreads friend) has inspired this post. It all started with my brief comment about the prospects of brewing on the ISS, up in the microgravity of low earth orbit. But before we get into space, let’s think about what happens during fermentation. (I’m going to mostly focus on beer in this post but similar comments could probably be made about wine).

Beer making in the Egyptian 6th dynasty (British Museum)
Beer making in the Egyptian 6th dynasty (British Museum)

People have been brewing beer for many thousands of years – in Egypt the process was well-organised long before 2000BC, and the earliest confirmed evidence for beer-making that I am aware of is from the 5th millennium BC, at Godan Tepe in modern Iran. I strongly suspect the history is much longer, and that more evidence will turn up in time.

Beer making has been credited with all kinds of benefits to humanity, including driving an early wave of technological development. Quite apart from the enjoyment factor. Back then, and for a great many years subsequently, beer was made in open fermentation vessels – basically very large pottery containers, semi-porous and so holding on to residues of yeast and the like. It was often a spin-off of the bread-making industry, seeing as how you needed yeasts and grains for both. Both bread- and beer-making have had, at times, vaguely magical or alchemical associations – these very ordinary foodstuffs are hidden away in a very ordinary vessel, and over the course of a few days they transform into something quite extraordinary. In early times, hops were not added (this seems to have been introduced in the middle ages), but people did sometimes add other flavourings such as fruit or spice extracts.

Now, during fermentation the yeasts work with the various sugars in the raw mixture, together with oxygen in the air at the top surface, and convert these into alcohol and CO2. The process is self-limiting – yeasts eventually kill themselves in too high a proportion of alcohol, so fermentation slows and stops. A brewer can choose whether to let the process go on to completion, or stop it early. An early finish means lower abv (alcohol by volume… the strength of the brew) and a sweeter drink. In olden days, I suspect brewers had conventions about how many days to leave the mixture – nowadays brewers have a more mathematical set of targets to do with final abv balanced against taste. Also, large breweries are very interested in keeping consecutive batches consistent about strength and flavour, whereas a domestic brewer, or someone in pre-industrial days, was less bothered about this.

Finally, carbonation. If you are brewing in an open-top vessel, all the CO2 generated simply goes out into the air. And if you are brewing at room temperature, especially in a hot climate like Egypt, not much gas is held in the liquid anyway. Nowadays we brew and store beer at specific temperatures in order to achieve a target level of carbonation. The colder the beer, the more gas it can retain, and then release as the drinker opens it up at room temperature. You brew for the preferences of your target market – lots of fizz (as in many lagers) or hardly any (as in many real ales).

Fermentation vessels - Grasmere
Fermentation vessels – Grasmere

That brings us onto the specific issue that triggered these fine discussions. What happens in low gravity? Not a problem in ancient Egypt, but looking ahead it’s an issue we will want to solve. Consider a modern fermentation vessel – a cylinder, usually with a cone at the base, and considerably taller than a person. As yeast ferments here on earth, different groups of yeasts arrange themselves at different levels in the vessel – some near the top and others near the bottom. This reflects slightly different ways in which they turn the sugars into alcohol… the sugar level varies in a gradient as you go up and down the vessel. As the yeast becomes exhausted, and starts to die because of the alcohol percentage, the yeast particles sink into the cone, taking with them some of the other residues like hops, grain particles and so on. The beer slowly clarifies by itself, though most brewers also use specific methods to end up with a clear rather than cloudy beer.

That’s fine here on Earth… but in orbit several problems arise. First, there is no real sense of up and down. So a yeast that is used to being near the top of a vessel, with its preferred environment of sugars and whatever, does not know where to go. Likewise, as they finish their job and die from overindulgence in alcohol, there is no “down” direction into which they can settle. Finally, there’s no particular reason why the liquid would stay in one clump – you could easily end up with several disjoint blobs of liquid, with varying proportions of the yeast you had added, each fermenting to different extents.

Centrifugal Fermenter (speculative!)
Centrifugal Fermenter (speculative!)

So this was the point I got to in my Goodreads discussion, which triggered several follow-up chats here in Grasmere. Not that we’re (yet) planing on an orbital version of our various beers and ales, but it is good to be ready for the future! The best answer we could come up with was to artificially introduce a sense of up and down by means of a kind of slow-speed centrifuge. Not so fast as to drive all the solid matter to the outside too quickly, seeing as you need it spread through the liquid at first, but fast enough that the liquid stays in one body, and the yeast can tell which tell which way is up and down. (As a side issue, you’d probably want two of these, rotating in opposite directions, so as not to off-balance the space station itself).

The fermentation will generate CO2, and you don’t want to just dump that into the cabin air supply, so you capture that with a safety valve coming out along the spindle (the “top” of the vessel). That can then either be kept for later use – as many breweries fixed here on Earth do, so as to reuse a resource which costs real money – or fed slowly back into whatever air-purification system takes your fancy. When the time comes to clarify your beer, you just spin the centrifuge faster and let the solid particles accumulate in the “bottom”, taking the splendidly clear beverage out of the “top”.

Bottling would be an interesting task, since yet again it is something that here on Earth relies on gravity as well as some back-pressure to get the liquid where you want it to go. But if you’ve successfully got this far, I’m sure that the final stage of getting your finished beer into some kind of container would not be an insuperable problem. In orbit you want low carbonation anyway – the last thing you want is for some rogue container to fob frothy mix all around the interior of your capsule. So you keep the whole thing chilled, to hold the gas in suspension in the liquid, and in any case you aim for a quiet liquid rather than a lively one! And voila – you have Orbital Beer, and happy astronauts…

As mentioned very briefly in Far from the Spaceports, concerning the legendary Frag Rockers bar,

“You’ll need to go to Frag Rockers to get anything decent. Regular fermentation goes weird in low gravity. But Glyndwr has got some method for doing it right. He won’t tell anyone what.”

For the curious, here is a British Museum video of recreating an ancient beer-making process based on what we know of ancient Egypt…

 

Laws, qualifications, and the drinking of alcohol

University of Cumbria at Barrow - where I took the course
University of Cumbria at Barrow – where I took the course

I heard today that I had passed the study element of a Personal Alcohol Licence, which (after I have gone through a police background check and a few other formalities) allows me to authorise the sale of alcohol in England and Wales. Not in Scotland, Northern Ireland, or indeed anywhere else in the world, but I guess you have to start somewhere.

Now, this is far from my most advanced academic qualification, but the intriguing thing about this one is that it legally entitles me to supervise – and therefore take legal responsibility for – the public sale of what is undoubtedly a kind of drug. Without the licence, I can work under someone else’s supervision, but cannot just set up and flog booze on my own account. With it, and subject to a bunch of other constraints, I can do just that.

You can imagine that a fair proportion of the material, and the final test, focused around UK law relating to drink. There are obvious things to do with the age of the drinker, but I also learned that it is a specific legal offence to sell alcohol to someone who (in the considered opinion of the seller) is already drunk. Too much like shooting fish in a barrel, I suppose. Most of the laws fit around common sense, though as with any body of legal material you are left a little perplexed as to why specific conditions were imposed.

Anyway, all this set me thinking about law and qualification. The government of the day, however it was decided, has for a very long time indeed decided that it is entitled to a certain proportion of the profits from various kind of sales – and alcohol has typically been way up the list. And of course where rulers try to enforce a ruler, some subjects will concoct cunning schemes to get around the additional expense – excise duty spawns groups of smugglers almost by definition. But you only risk smuggling goods where the financial equation makes sense – small, easily concealed items where the tax duty is high enough that you can pocket a decent cut for yourself, while still leaving the buyer feeling they have done very well out of the deal.

So customs duties, and the body of regulations which underpin them, have been around for millennia. And – typically – part of those regulations consists of ways to appoint specific individuals as those few who are allowed to make transactions. In days of old, one suspects that many of these appointments were based on nepotism or bribery… if you had the right connections, or could stump up enough starting cash, you could find yourself in a comfortable position and set up for life. Nowadays the process is rather more transparent, and the barriers to entry are very much lower.

But equally, things have been tightened up in other ways. A couple of hundred years ago, it was fairly common for ex servicemen to use their prize money, or sign-off pay, or whatever they had saved up, to buy a little inn somewhere, and make a tidy living brewing or distilling booze of widely varying quality, and plying locals with the results. (Any pub you find called the Marquis of Granby recalls charitable donations by this 18th century gentleman who donated money to wounded servicemen). Provided you could afford a small building and a few bits and pieces to do the fermentation, you could set yourself up, no questions asked. These days, you have to go through hoops like planning permission, health and safety, police, plus of course getting a premises licence. There are all kinds of reasons why an apparently sound business plan might be rejected by officialdom.

The ISS (NASA/JPL)
The ISS (NASA/JPL)

So that is looking back… but what about forwards? Right now the only human outpost we have away from the Earth is the ISS. It’s not very far away – about 400km above the surface of the Earth, less than the distance from one end of England to the other. And I don’t suppose that the occupants have much privacy or opportunity to set up fermentation or a distillery up there. Though I did hear today that Budweiser has funded one of the science experiments on board, seeking to improve strains of barley with increased resistance to environmental stress. So maybe next year someone wil fund a experiment to make beer up there and see how yeasts behave in microgravity!

But let’s assume that within the next couple of decades we have an outpost or two somewhere else – the Moon, say, or Mars, or even a privately operated space station. How likely is it that nobody will attempt to ferment fruit or vegetable juices? And whose laws will be applied to regulate such an operation? Now run the scenario on a few more years, into the solar system I imagine for Far from the Spaceports and its sequels. There are a decent number of scattered habitats, each separated from the others by at least days, often weeks, and sometimes months of travel time. It will, I suspect, become impossible to try to enforce some kind of uniform system of laws.

Alexa Timing logo

My guess is that each habitat will have its own local set of laws and customs – no doubt broadly consistent with each other, but differing in detail. Sure, you can send a message anywhere in the solar system within a day at most, but if you get a tip-off that the habitat on Charon is bootlegging some kind of moonshine drink that is not allowed on the Moon, it’s going to take your police three or four months to trek out there and investigate. Will they bother? In that kind of situation, I don’t think it is feasible to try to maintain a single unified system of laws and regulations. So now suppose I have trained for my personal alcohol licence here on Earth (which in fact I did), and then decide on a whim to travel out to Charon. Will a publican out there recognise my licence? Or will he or she make me study for a duplicate one, ending up with a signature of someone on Charon rather than Earth? Right now, in the present day, it is extraordinarily hard to transfer qualifications between countries in professions like teaching, nursing, psychotherapy, and so on – will things be any different when we’re scattered across a few dozen habitats? I suspect not, especially as my own new licence doesn’t even allow me to do stuff in Scotland!

All of which is why I like writing about that near-future band of time, when there is no Federation, no Galactic Empire, or whatever – only local enforcement of issues according to moral and social principles which makes sense to the occupants. I suspect the chief coordinating factor would be economic – if you felt that some particular habitat was doing things the wrong way, you wouldn’t trade with them. They would become isolated, and there’s nowhere in the solar system away from Earth that can actually be self-sufficient. Hence I write about economic and financial crime, as these are the things that seriously threaten lives and livelihoods.

Compost

Before I start on compost, here’s a remarkable picture of Mars taken with a fairly ordinary camera, from a spaceship about the size of an average briefcase. Called a CubeSat, two of these were launched alongside the Mars Insight probe, and whistled past Mars while said probe made its way to a safe landing. More about Mars later…

It’s the time of year when – at least in the northern hemisphere – you put compost on your garden as part of bedding it down for the winter. These days that’s generally easy – you trot along to your local garden centre and get 3 bags for £12, or whatever the deal is, and you spend a suitable amount of time distributing it around your little patch. Someone else has done most of the hard work of transforming original plant and animal matter into an easy-to-use commodity.

But in a big garden you can do things a bit differently (and if you’re a farmer, you’ll be up into another league altogether, which I am not going to presume to write about). You can gather up said plant and animal matter yourself, stow it away somewhere dark and warm, add whatever extra bits and pieces you want, wait the better part of a year… and there you have your own compost. Which is what has been happening up here in Grasmere – last year’s rotted stuff, including pig manure, was ready for distribution. Not only that, but all those leaves which have been building up in the garden got put into the compost bins, waiting for their turn next year!

Now, this process has been going on pretty much ever since people discovered how to cultivate crops. Last year’s plant waste, together with stuff from whatever animals you had, and most likely human waste as well, got stashed away and spread on the fields when ready. The process has got steadily more scientific over the years, with additives to ensure that the ratios of chemicals are appropriate for the crops in question, but fundamentally nothing has changed.

But now think about what happens when you go out into space. You can grow some crops hydroponically, but this needs water which has been prepared with suitable levels of nutrients… which needs those nutrients to be available. We’ve done it up on the ISS, where the astronauts have prepared bits and pieces of salad to accompany their regular rations. But most of what is eaten in orbit has had to be carried there in a cargo supply ship. Suppose we add a couple of large modules on to the ISS and start growing things on a bigger scale. Then maybe we just need to ship the nutrients up there. That helps.

Now go a bit further. You have built a moonbase, or are living in a dome on Mars, and you want to grow your own stuff. In one sense you are surrounded by soil, but it is totally lifeless soil. It probably has a number of the basic chemicals you need, but none of the complex organic substances that your plants need. So you’re back to shipped-in nutrients… until you have either built up some human waste (and allowed it to decompose in some suitable way), or waited a year for the spare bits and pieces from one year’s harvest to rot down into compost.

This is probably reminding you of The Martian – Mark Watney manages to grow potatoes using the left-behind waste of his fellow crew-members. It goes pretty well until an accident exposes all his carefully prepared plants and compost to sub-zero temperatures and an air pressure less than that on Everest… which kills the lot and causes him to revert to Plan B (or probably, Plan F by that stage in the book). All necessary stuff, and emphasising the point that to grow Earth plants, you have to have built up a stock of Earth compost to encourage their growth.

So as I was piling leaves into the compost houses to being their long process of rotting down for this time next year, I suddenly wondered about our future. Out of all the unlikely cargos to be shipped out to our future colonies out on the Moon, Mars, the asteroids, and wherever else, wouldn’t it be supremely funny if most of them were shipping out the raw ingredients to make compost? Not an eventuality that makes its way into fiction very much… but how else are you going to grow your food?

Fire

The empty fireplace
The empty fireplace

This week I helped swap over an old wood-burning stove for a new one. As has been my experience of all practical jobs, what had promised to be a fairly straightforward out-with-the-old-and-in-with-the-new process ended up having unexpected wrinkles. The chimney pot also needed replacing (since the old fire didn’t draw very well), and a new chimney liner had to be put in. And there was an old liner which had to be pulled out – both liners follow a chimney which is about ten or eleven metres high, so these were interesting tasks in themselves.

Then an old hearth had to be taken out (which has already happened in the picture above, thanks to the very large drill on the floor, plus a sledgehammer and other hefty tools). Then the new stove had to be moved into position and the exit pipe fastened to the chimney liner with suitable gunk.

Then the paintwork had to be touched up where it had been bashed about by all this. And finally the copious amounts of dust – from stone, soot, brick and ash – had to be cleaned up on pretty much every surface in the room!

The story has a happy ending – the new fire really does light, as you’ll see below, and early impressions are that it is doing a better job than the old one. But while doing this job, I had plenty of time to contemplate fire. Or more widely, energy.

There are some places on planet Earth where people can live without using any energy source for heating, though most places need something at least in wintertime. But every society that I know of, world-wide, has harnessed fire for cooking. This isn’t just for aesthetic or culinary satisfaction – the process of cooking food makes a much wider range of nutrients accessible to our digestive system in much more reliable quantities. So the harnessing of fire for cooking – something like a couple of million years ago, give or take – liberated our hominid ancestors to get on with other things rather than have to forage endlessly. They could prepare food so as to use it more efficiently, and store it so as to survive lean times.

They could invent fish hooks and jewellery in their spare time, create artwork and conduct sacred ceremonies. (They also designed weapons of increasing effectiveness, and social orders which exaggerated differences in wealth between individuals, but we’ll skip over that for today). The use of fire for cooking seems to coincide with one of those great leaps forward in the often-slow process of human development, signalling this opportunity for our remote ancestors to explore and comprehend their world with intelligence.

Cover – In a Milk and Honeyed Land

All this happened in remote prehistory – long before the Late Bronze Age of In a Milk and Honeyed Land and its sequels, and long before the Langdale world where Quarry will be mainly set. By those times, fire and cooking were established parts of life whose origins were lost in the unfathomable world of the ancestors. But fire – energy – has remained a key part of our expanding world. Our ability to inhabit every part of the world has relied totally on our ability to maintain adequate warmth in our houses. An unprotected human in the middle of an Antarctic winter wind would die within thirty minutes at most, and would be crippled long before that.

A wood-burning stove is basically a very old bit of technology – except the one I helped with was made of metal, which pushes the date much more recent. But the problem it is helping to solve is perennial. Nowadays we don’t actually need to burn wood to generate heat, though many people find the experience of being warmed by an actual fire to be more comforting and engaging than just switching on a radiator. Energy from many sources is fed into our electricity grid – coal, water, wind, oil, nuclear, solar – and whatever the source, it runs an electric fire very nicely. The choice of our national energy spectrum of sources is – and should be – made according to national and global considerations, not whether I personally happen to have one device or another.

And the situation become more stark as we go out into space. Space, as well as being mind-bogglingly big – is a weird place. In one sense it is freezing cold – a warm body will radiate away energy at a steady rate. But in another sense it is full of energy – light from the sun, electromagnetic radiation, and down at a quantum level a whole sea of vibrant energy just waiting to be collected. Whether we send out a robotic probe like Dawn, or we go elsewhere in person, we either take our energy with us or we collect it from the void around. The Juno probe has huge solar power collectors – each of those three panels in the picture is about the height of a typical house – and it is operating  almost at the outer limit of where such solar panels can be used. Probes that go further from the sun must carry their energy with them, and when it runs out they will die.

Most science fiction writers assume that the spaceships that they write about can refuel somewhere in space – maybe by gathering up interstellar hydrogen as they travel about using one variation or another of an idea of the physicist Robert Bussard – Poul Anderson’s Tau Zero was a relatively early novel making use of a Bussard ramjet, and at some stage Star Trek script writers decided that this was how the Enterprise and other similar ships gathered fuel (alongside matter-antimatter reactions and dilithium crystals). That way your ship can carry on boldly going without the inconvenience of having to stop at a nearby starbase just to load fuel into the necessary bunkers.

However it’s done, people will continue to need energy – fire – wherever they go. I think it’s most unlikely that energy sources in my science fiction books look anything like a wood-burning stove, but whatever they do look like, they serve the same purpose.

Invasion, migration and assimilation

Cover - 1066 and All That (Goodreads)
Cover – 1066 and All That (Goodreads)

Last weekend, a whole bunch of people, including a number of my online friends, have been remembering and reenacting the events surrounding the Battle of Hastings – 1066 and All That. It so happens that everyone I know who was at Hastings the other day favoured the Saxon side, from which perspective Harold is a fallen hero, who came so close to repelling the invaders in the south as well as the north. But I suppose that a great many of the participants took the Norman side, and so found themselves once again victorious.

In fact, most people I know prefer the Saxons, and harbour a deep-seated wish that things had gone differently. Perhaps this comes from a desire to cheer on the underdog, or from hearing about how viciously the Normans set about securing the land they had claimed (especially in the north). But I suspect it is also because we were brought up on tales of Robin Hood and his Merrie Men, striving as disenfranchised and downtrodden Saxons against their wicked and uncouth Norman overlords.

I have to admit that, personally, I struggle to see the Saxons as unequivocally the nice guys in our history. My own historical preference is earlier, often swimming in the uncertainty and veiled mystery of times before the written word gave us its particular perspective. And from my view, the Saxons (and Angles, etc) are new arrivals who themselves had claimed a new land by often violent methods. The tales of Arthur and his Companions, stripped of their courtly Medieval topcoat, tell us of a time when British and Welsh leaders tried to protect their homes from wave after wave of incoming aggressors.

Ultimately their stand was a failure – from south to north the Saxons defeated and occupied British land, and the points of resistance were only sandcastles in a rising tide. Perhaps the last to fall was Dunmail, in what we now call Cumbria. As this last king of the British lost his last battle, his last few loyal men took his crown and cast it into Grizedale Tarn, so the new usurper would not have the satisfaction of claiming it. Like Arthur, the promise is that Dunmail will – one day – arise again to claim his crown and kingdom.

So – making what I suspect are controversial statements – I kind of feel that there was something karmic in the events of 1066. The Saxons had arrived and pushed aside the earlier occupants, and now something very similar was happening to them.

Now, arrivals into a country are a curious thing. It’s worth thinking about how we reconstruct what happened. In the past we have had to rely on written perspectives, often put down on paper, papyrus, or clay many years later by the winners or their ancestors. Or we look at archaeological remains, which by their nature can only say so much about their owners. Did the same culture adopt new artefacts quite suddenly? Or did a new culture simply reuse the same things as their predecessors? Nowadays we can have a bit more insight from DNA testing, and the outcome of this has sometimes supported and sometimes challenged prior expectation. More of that later.

There are basically two ways that new arrivals interact with those people already there. Sometimes there is violent displacement of the old by the new. This seems to have happened in Bronze Age Britain, where there is hardly any genetic continuity between the Beaker People and their Neolithic precursors – the great stone monument builders have left almost nothing of their genetics throughout most of Britain. This DNA result rather overturned the prior thinking that the change represented a peaceful transfer of ideas.

Other times the old and new quietly absorb each other and are enriched by the process, playing out on a national or regional level the process of human reproduction, with all its delights and difficulties. Newcomers might arrive for all kinds of reasons, martial or peaceful, but after a few years one finds a fusion of the two emerging – a child of both originals.

Now, at the time of arrival, nobody knows what will happen, and it’s natural for the current inhabitants to fear and deride the incoming hoard. So the Saxons did to the Normans.. so the Britons did to the Saxons… so the Neoliths did to the Beaker People… and no doubt so the Neanderthals did to the Homo Sapiens clans. We still see this played out today, as nationalist politics finds innovative ways to arouse anxiety about “the other”. They’ll take our jobs… they’ll impose their religion… they’re not like us… slogans about “the other” can be found in pretty much every part of our world, fuelled by migrations and flights from war and famine. Personally I remain optimistic, and look for the creative fusion of cultures rather than the catastrophic collision. But looking back at history, it takes effort to find creativity, and we humans don’t always manage it.

Going back to DNA, there are still limitations. We can now – tentatively, and extrapolating from individual cases – identify where intercourse has combined the heredity of two cultures. So we know that the DNA map of Britain correlates pretty well with some historical events, and not with others. We know that pretty much all humans outside Africa have a significant percentage of Neanderthal DNA. We know that a teenage girl’s finger from Siberia shows her to be the child of one Neanderthal parent and one Denisovan parent, some 90,000 years ago. But what we don’t know is the circumstances of the intercourse. Was it a socially sanctioned event, even a personally consenting one? Or was it something darker, the result of forced prostitution or rape? DNA cannot tell us, but that’s the kind of detail we would like in order to uncover the interactions of peoples. It’s one of the great anxieties of mankind – do the newcomers arrive in peace or war?

High Street, ancient trackways, and Romans

As well as Boot and the Hardknott Pass, which I’ve been talking about the last couple of weeks, I spent a fair amount of time around Ullswater while in Cumbria. It’s the second longest of the lakes (after Windermere) and has often been claimed to be the most aesthetically pleasing. For example, Wainwright called it, “that loveliest of lakes, curving gracefully into the far distance“. Be that as it may, it certainly has a wealth of natural beauty and historical interest. But the fact that at many points around its shores, the hills encroach very steeply, means that it is only thinly settled, and parts of it are quite difficult to approach except on foot or by using one of the several launches that go to and fro.

The particular part I want to focus on runs down the eastern side of the lake. It is another part of the Cumbrian network of ancient trackways – later adopted by the Romans for their own purposes. This one is now called High Street, running by the hill of that name a little further south, and ultimately connects to Ambleside… and hence Hardknott, Boot, and the coast.

The Cockpit, looking roughly south
The Cockpit, looking roughly south

My starting point, after some gentle approach climbing up from the lake, was at an ancient stone circle called The Cockpit. Nobody knows the original name, or indeed the original purpose. It probably dates from the Bronze Age, could be up to about 5000 years old and is one component of a large collection of ancient sites on Moor Divock. Whenever and whyever it was built, it lay then as now on a crossroads. A roughly north-south route from Penrith to Ambleside crosses a roughly east-west route coming across from Castlerigg (near Keswick) to the Eden Valley and Shap. The much later Romans would be making similar journeys, though they were more interested in their settlement near Cockermouth than in looking at the Castlerigg stone circle. And nowadays casual explorers like me go there.

So from The Cockpit you head south – like Burnmoor near Boot, the current terrain is wild and slightly boggy, but back in the days of prehistoric occupation it was rather more pleasant. There’s a long steady climb up towards Loadpot Hill, but well before you get there you can see many of lakeland’s most dramatic peaks in the distance – Blencathra, Skiddaw, the whole length of the Helvellyn ridge, and then Fairfield and others heading south. You also regularly see other signs of human occupation, from other prehistoric arrangements of stones through Roman mileposts, to a very few much more recent (and ruined) dwellings. The track itself stretches out in front of you, and there’s a real sense of walking in the footsteps of a whole throng of ancestors. You really could walk on through the Kirkstone Pass and down to the shores of Windermere, provided you were equipped for the journey.

(Former) Roman altar, old St Martin's church

I didn’t do that, but turned off the ridge into Martindale, where one last historical treat awaits. The current old church of St Martin’s dates from Elizabethan times, but a church has been there since the Middle Ages. The font – which has been used there for some 500 years – was originally a Roman altar, retrieved by some enterprising villagers from somewhere along High Street. In the graveyard is an ancient yew, which some believe is among the oldest living trees in England and could be up to 1300 years old. That would probably predate the first appearance of Christianity here, and would mean that, like the Roman altar, it had once been involved in very different expressions of spirituality.

All in all a great walk, and one to revisit at some stage. And, of course, all good raw material to stir into the (pre)historical novel Quarry which is slowly coming together in my mind.
