Agricultural Surplus is a Dangerous Idea

A lot of historians throw around the term ‘agricultural surplus.’ By this they mean food which the farmers and their livestock don’t eat, and which can be used to feed stonemastons and metalworkers and scribes and priests and gentlemen farmers. In this theory, societies have to find a way to produce a larger surplus before they can produce things historians like such as books. I think this term is one of the terms which historians borrowed from economists in the early 20th century.
At first the idea seems harmless enough: if a family needs 20 bushels of barley to feed itself and its animals and have seed for next year, and they harvest 30, they will probably trade 10 for something else or use it to fatten stock. But in the real world there is rent and taxation. And when you look at the science of nutrition, you find that there is a range in the amount of food that farm workers eat. At the low end, they can’t work very well, lose most of their children, and die young of chronic diseases or infections which their weakened body can’t fight off; at the high end, they have a varied diet, grow taller and stronger, and can be pretty sure of having surviving children. Its not actually the case that people need a certain number of calories of Generic Food ™ a day, above which they just get fat and below which they die. Taxes and rents often come out of this margin in between. And it is usually taxes and rents which pay for the stone buildings, the scholars writing treatises on ethics, and the beautiful silver cups.
Two Dresses a Year

For 10,000 years or so, clothing was so expensive that most people could only afford a few outfits. Then over the past lifetime they suddenly became so cheap that for people in a rich country, storage space is the main concern. We see traces of this in inventories of family property during divorces outside the Valley of the Kings, in Babylonian invoices for one suit of clothing per soldier per year, and then in medieval post-mortem inventories and sumptuary laws, but it continued later than we like to remember. A snatch of old verse was stuck in Robert Heinlein’s head:
There’s a pawn shop on the corner
Where I usually keep my overcoat.
Now, today a synthetic winter coat would hardly be worth pawning (a day’s minimum wage?), but a woollen one of 2-5 yards of fulled cloth could last decades and cost accordingly. A passage by George Bernard Shaw touches on this from another angle.
More Numbers with Curious Echoes
Its a strange fact that the kind of hyperbolic numbers which Greek writers use for barbarian armies sometimes occur in the Old Testament, but rarely in other texts in Semitic languages. But if you look at numbers as part of a broad west Eurasian world, you sometimes still notice echoes. There is an inscription written... Continue reading: More Numbers with Curious Echoes
Good King Robert’s Testament

Throughout the long five hundred years of war between Scottish and English kings, the Scots tended to win the wars but lose the big battles. Scotland was a smaller and poorer kingdom, and the way of fighting battles that the Scots were good at (lining up big masses of spearmen and axemen with jacks and steel caps) was not very effective against the way that the English were good at (dismounting their armed men and galling the enemy with arrows until they charged, breaking formation as they came because no prince in Europe could keep a large army together long enough to drill it). A fourteen-line gem of a poem describes the way of fighting which proved most successful in campaign after campaign:
On fut suld be all Scottis weire, // weire = Wehr “defense”
– After Sir Charles Oman, A History of the Art of War: The Middle Ages from the Fourth to the Fourteenth Century. New and Cheaper Issue (Meuthen & Co.: London, 1905) p. 579 https://archive.org/details/historyofartofw00oman/
By hyll and mosse themself to reare. // reare: roar? an earlier edition has weire “defend”
Lat woods for wallis be bow and speire,
That innymeis do them na deire.
In strait placis gar keep all store,
And byrnen ye planeland thaim before.
Thane sall thai pass away in haist
Wenn that thai find na thing but waist.
With wykes and waykings of the nyght // wyke: wake
And mekill noyis maid on hytht, // mekill: big, large
Thaime sall ye turnen with gret affrai, // affray: fright, alarm
As thai ware chassit with swerd away.
This is the counsall and intent
Of gud King Robert’s testiment.
Now roll that around in your mouth a bit and savour it. Enjoy the language and the rhythm and the joy with which it describes something horrible in ways that poor crofters and shepherds can understand. Think about how rare it is to have something like this from the side which was wise to avoid battle. And then if you really must, go on where I ask my annoying academic question, namely where does this poem come from?

Quite a few people interested in ancient warfare know an article by one F. Maurice on the water and roads at the Hellespont. After reading Herodotus’ story that Xerxes marched through the area with 1,700,000 infantry, 80,000 cavalry, and 20,000 charioteers and camel-riders and hiking around the countryside in summer, he argues that an army of 150,000 soldiers, 60,000 noncombatants, and 75,000 animals is the absolute maximum that could have been fed and watered in the area (paragraphs 10, 21, 33). I think this was the Major-General Sir Frederick Barton Maurice who was forced out of the British Army for political reasons in 1918, became a journalist and an advocate for veterans, and died on 1 May 1951. People cite it because he was an experienced staff officer who had walked the ground and talked to classicists like J.A.R. Munro. Its full of details such as that the British Expeditionary Force of 72,000 men, with railroads for supply but just horses for transport, needed 20 square miles for its camp in 1914 (the cavalry were stationed elsewhere and the motor vehicles had not yet arrived). But its certainly not the last say, and while he was talking to British classicists, a retired Bavarian general was preparing a study of the same problem and addressing their arguments.
One Robert von Fischer (d. 1937) commanded the 1st Royal Bavarian Landwehr Division in France from September 1914 to December 1915 and received the honorary title of Bavarian General of Infantry in 1917. He had similar military credentials as Maurice: he commanded a division on the Western Front for 16 months, Maurice served in the Tirah Expedition in Afghanistan, the Boer War, and briefly on the Western Front. And after examining the whole route and the problems involved, he felt that the Persian army was probably no more than 40,000 soldiers strong.
Climbing Down Slowly
Early in my time in Innsbruck, they held a rock climbing world championship in the square outside the Markthalle. A few years later a new rock climbing centre opened near the railway arcade, and all the playgrounds sprouted climbing walls like potatoes kept too long in a heated room. At the beginning of May, there was a rock climbing European championship in Innsbruck. When you listen to interviews with officials, you can see that this all fits into a simple policy.

Squatters not Owners on the Web

Many of the problems with Internet communities today stem from the fact that they are in places which don’t belong to the members. Youtube and twitter are nothing without their users, but Youtube and twitter are free to reject someone or change their standards of what is acceptable at any time, and users have no grounds to challenge them. Years of work can be deleted or hidden in a moment if the owner sees fit, and standards of behaviour designed to keep billions of people clicking are never going to be the ones which a small group of nerdy people chose for themselves. Moreover, its not in the interest of these companies to let users export their work in a convenient format.
Alexiares suggests that a good first step would be moving to services hosted by the post office or the public library. The public post has its problems, like the times it was used to block the spread of birth control information and equipment, but libraries and the post office at least have a tradition of offering service and privacy to everyone on equal terms, and are at least based in the same country with the same laws as their users. I don’t think that Germans and Americans will ever agree on what is protected free speech, or people in Ontario and people in Fars will agree on who can bare which bits. So decentralizing onto services like mastodon could help.
When I think back, though, it seems to me that this is a much older problem than centralized social media. In the 2000s, communities sprang up in places like the comments sections of blogs or the off-topic section of forums. Often, the owners of those sites are not happy about this at all, because moderation is work and organizing moderators is work and they have plenty of underpaid work of their own to do (the Tayler family of webcartoonists shut down comments on their main site for this reason). Other times, they create a monthly thread or a members-only subforum to let their readers get it out of their system. But they have do do something because people often use an online space designed for one activity for another.
