Meditations on a Homespun Blanket

I have some camping planned for later this summer, so I bought a woolen blanket from Adam Henzl at https://handwovenwool.com/ It was probably woven in the Achaemenid empire, and the price was similar to a 100% wool blanket from sellers of Heimtextilien in Innsbruck. The wool is soft and well-woven with strong selvages. When I spread it over my lap and worked it, I found it very educational.
As you can see, the wool still contained a significant amount of burrs, grasses, wood chips and windblown debris. Much of this was not easily visible but appeared under my hands and my tweezers.

Some Thoughts on “The Cosmic Computer”

On Canada Day 2017 I finished re-reading the project Gutenberg text of Piper’s Cosmic Computer (my paperback copy with the wonderful red-and-purple cover is back in Canada). I read this novel every few years, and I always learn something new. Quite a few people who grew up on the American science fiction of the 1940s through 1970s have been reading the news, finding something uncomfortably familiar, and looking back to those Silver Age writers to understand some current madness (Phil Paine reread Revolt in 2100 for the same reason). I can’t talk about that here, but I want to talk about some of the things which I found valuable in this novel.

One would think that someone coming this way on a cycle with headlights and reflectors would need to watch out to the right and bear a little bit left, since cyclists coming from the left can see you coming and slow down if they want to make the turn onto the...

The Power of Old Books

For the last few weeks I have been trying to follow a lead on the origin of the idea that the Greeks made armour by gluing layers of linen together. Everyone who believes this theory today seems to have got it from the late Peter Connolly, but some of my American friends have found versions as early as 1869 (if you know of an earlier text linking glue and armour, please say so in the comments!) I think I can link it to Isaac Casaubon and another famous 16th century scholar, and show how between 1868 and 1875 their theory of linen soaked in vinegar until it became like felt turned into Connolly’s theory of linen soaked in glue until it became like a mask of bandages soaked in plaster. But my case for that will appear in a footnoted article not a blog post, and today I want to make a larger point which is useful even if you have never spent 10 minutes ranting about silly theories of armour construction.
Everyone with a browser and an uncensored Internet connection is two clicks away from every book in a great library. And if you chose to learn to use it, you can discover wonderful things known to very few people in this world. There are rooms full of books which which are interesting to some community today which have either been forgotten, or were never brought to the attention of that community because it did not exist in 1881. Armour in Texts might seem impressive, but most of the works there were quoted or summarized in about three books published before I was born. I did not find most of them by reading sources, I found most of them by reading people who had read sources and noted down which were useful for understanding armour. The farther back I dig into scholarly books on armour, the more interesting sources I find which nobody seems to read.
It helps if you can read even a little bit of any major language other than English, and if you know a little bit about 19th and early 20th century culture to spot the Edwardian equivalent of Osprey books and self-published treatises on how mainstream science is totally wrong. But I know plenty of people without a lot of university education or knowledge of other languages who have still found and copied useful things. This work is too big for me: I have a dissertation to finish, and I do not love every kind of learning equally.
Google Books and archive.org are the best known collections of digitized books, but even more useful are French projects like Persee and Gallica and German projects by the Bayerische Staatsbibliothek and the University of Kassel. These projects are run by libraries and universities, and librarians are expert in putting books away in a place where they can be found again, and in warning people about issues like the different forms of letters used before the 20th century. (Google rushed to scan books and refused to listen to librarians, so about a third of their books are mis-catalogued and many have transcriptions which make basic blunders like confusing ʃ and f … and it is much more expensive to correct these mistakes after they have been scanned and processed than it would have been if they had moved more slowly and done it right the first time). But having any of these resources is a treasure, and it gives you powers which were once limited to people living in Vienna or Paris or London.
2017 Year-Ender
Another year ends in the manner of the one which ended Xenophon’s Hellenica: after terrible battles and startling results, there is not peace but confusion and disorder. Xenophon’s perplexity lead to a Sacred War, 300 dead lions on the plain of Chaeronea, and the King dead in an abandoned carriage as his conqueror bent down and took his seal with clean white hands. As for me, I am getting to know the local deer and my old library.

How Much Did a Shirt Really Cost in the Middle Ages?

Some people on the Internet are curious about how much a shirt cost in the middle ages. Now you could try to answer that question by trying to calculate how long it would take to spin and weave the linen and sew the shirt, combining your guesses in an elaborate chain of assumptions using your modern education. A certain Eve Fisher imagined and calculated and came up with the figures $3500 or $4200 for a shirt like those depicted by painters like Peter Brueghel the Elder. This has been re-posted by a number of popular websites, and several weavers and spinners have dropped by her website to comment that they are not so sure about some of her assumptions. But did you know that we can skip all of these guesses and calculations, and the questions which they pose about whether we spin and weave as fast as people in the past, and just ask medieval people how much they paid for a shirt?
