Bone skates in De Proefkeuken

De Proefkeuken is a Dutch children’s show about science. In one episode, the two protagonists, Willem and Pieter, make their own skates.

One of their homemade bone skates.

They go to the Schaatsmuseum Hindelopen and see bone skates at about 6:20. Then they go back to their lab and create their own bone skates. They do not use the right bones and attach cords in a way that may cause extra friction on the ice.

They take them out for a test skate on badly chewed-up and snow-covered ice and find that they don’t work well. This is consistent with my experience: bone skates do not work well when the ice is rough and covered in snow. With smooth new ice they would have worked better!

The skates they take out to the ice do not appear to be the same as the ones they made in the lab.

The bone skates part of the film ends at about 9:30. At about 15:30 a sequence depicting a blacksmith making modern speed skates begins. They have more success with those skates.

The new bone skate from Přerov

In the second half of March, Google sent me a bunch of news articles about a bone skate found in Přerov, a city in the Czech Republic. This post is a summary meant to track the evolution of the story. There are of course many more articles and blog posts about this skate. I doubt this blog post will get picked up by Google’s alerts.

On March 14, Radio Prague International broke the news with an article by Ruth Fraňková that included photos and an audio interview with archaeologist Zdeněk Schenk with an English voice-over. That audio was the source for the interview fragments quoted over the next few weeks.

Schenk and his team dated the skate to the 10th or 11th century. It was made from a horse metapodium with the toe pointed and upswept. There is a small hole at the front and another (not mentioned in the first few articles) at the back.

All these articles focus on the “tools” aspect of bone skates, suggesting that people used them to travel and carry stuff across frozen waterways. This contrasts with the evidence from Scandinavia, where skates were generally used for fun. But so far, the articles are pretty good about sticking to the facts and providing correct information.

Google sent me its first update the next day, March 15. That link was to an article on BNN with the headline “Archaeologists Unearth Thousand-Year-Old Bone Ice Skate in Moravian City of Přerov”. Unfortunately the link doesn’t work any more.

A couple of other articles covering basically the same information appeared in the next few days. Mark Milligan published an article about the skate in Heritage Daily on March 16, and the Times of India published an anonymous article that, as of this writing, was last updated on March 18.

On March 20, Oguz Buyukyildirim provided a few more details in an article on Arkeonews: The bone is a metacarpus, and similar skates have been found in the past. Buyukyildirim cites specifically one skate found in 2009, but adds that “more such blades have been unearthed over the years in the wider area of the city.”

The next few articles didn’t add much other than a few more quotes from Schenk’s interview:

  • Christopher Plain‘s longer investigation, published on March 21 in the Debrief, quotes Schenk a few times as he describes skating with a pole and other skates from Central Europe and Scandinavia, especially in Viking settlements.
  • Abdul Moeed‘s article, published that same day in the Greek Reporter, gets more excited about the Vikings, but doesn’t provide any new information.
  • Amber Breese‘s article, published the very next day (March 22), includes some of the same details.

Slightly later, some more details emerged in a Newsweek article published on March 23 and updated on March 26. Now the skate has an additional hole at the heel. The article also mentions another skate found in the same city in 2009 and “nearly identical” skates found in specific places: Birka, York, and Dublin.

Things started to go off the rails on March 25, when Deseret News published Xochitl Bott Rivera’s article “Did archaeologists find the oldest ice skate ever?”. The correct answer to that is, of course, “No”. The oldest skates are close to 3000 years older than this one. Eventually the article does admit that, citing the Chinese skates found not too long ago. Along the way, it quotes Federico Formenti via Smithsonian Magazine.

The skate remained popular in various news outlets a bit longer; subsequent articles stuck to the facts quoted in earlier articles:

  • Angel Saunders’ article “1,000-Year-Old Ice Skate Discovered in Czech Republic, But It’s Not Made of Metal” was published in Yahoo! Life and People on March 25 and in Prague Morning on March 26.
  • Sonja Anderson’s article, which appeared in Smithsonian Magazine and MSN on March 28, includes a nice retrospective on the Schenk’s childhood skating on the same river.
  • The BBC covered the find on March 30.
  • Samantha Franco published an article in The Vintage News on April 1.
  • Emily Chan published an article in Chip Chick on April 4.
  • Andy Corbley’s article in Good News Network, published on April 5, includes the retrospective from Anderson’s article as a quote from GNN’s interview with Schenk.

As for the skate’s future, Prague Radio and Oguz Buyukyildirim note that it will be put on display at the Comenius Museum in Přerov Castle.

The thousand-year-old skate discovered by archaeologists in Přerov will soon be shown to the public. It will go on display at the city’s castle as part of an exhibition dedicated to the history of the region.

Skating in Comenius’s Orbis sensualium pictis

Comparing what a few editions of Comenius have to say about skating is interesting. Each edition includes Latin and one or more other languages. Let’s start with a later Swedish one.

Woodcut from Johannes Amos Comenius’s Orbis sensualium pictus (1775 reprint)

Pueri exercent se cursu, sive super glaciem 1 diabāthris 2, ubi etiam vehuntur trabis 3

Gossar öfwa sig antingen på isen 1 med skridskor 2, där de ock åka på kälkar 3

Les enfans s’exercent à courir ou sur la glace 1 avec des patens 2, ou à se aussi tirer dans des traineaux 3

(Boys exercise themselves on the ice (1) with skates (2), there they also ride on sleds (3).)

Johannes Amos Comenius’s Orbis sensualium pictus (1775 reprint), no. 136. The English translation is mine.

The 1775 edition is pretty basic. It calls skates diabāthris in Latin, skridskor in Swedish, and patens in French. The text matches German edition from 1669, which says that they ran on the ice with Schlittschuhen (diabáthris in Latin) (p. 279). The English version from 1729 has the boys running in “Scrick Shoes” (diabatris in Latin) (p. 171).

An older Swedish version has a different picture (though it’s the same as the picture in the German & English versions I checked) and adds another skating option.

Woodcut from Johannes Amos Comenius’s Orbis sensualium pictus (1689 reprint)

Pueri exercent se cursu sive super glaciem 1 diabatbris, 2 ubi etiam vehuntur trahis; 3

Gossar öfwa sig i löpande antingen vppå Iisen 1 medh skrikskoor/2 ijsläggior hwarestthe oc åka på kålkar: 3

(Boys exercise themselves by running on the ice (1) with skates/ice-legs where they also ride on sleds (3))

Johannes Amos Comenius’s Orbis sensualium pictus (1689 reprint), p. 281. The English translation is mine.
Detail from p. 281 of Comenius (1689 reprint). “ijsläggior” is crunched into the corner.

In this one, the word for (metal-bladed) skates is skrikskoor. The word for bone skates, isläggior, is also used. The boys played on both, apparently. But the bone skates are stuck in at the side, where there’s just barely enough space to fit them.

It seems like this version of the book was aimed more at country people; skriksko is a dialectal variant of skridsko in Swedish, and bone skates remained in use in rural areas for much longer than they did in the cities.

Meister Eckhart’s magic shoes

In sermon #15 of the Paradisus anime intelligentis, Meister Eckhart mentions two magic shoes:

Nû schrît, edeliu sêle, ziuch ane dîne schrittschuohe, daz ist verstantnisse und minne.

(Now go, noble soul, put on your walking boots, i.e., understanding and love.)

Sturlese & Vinzent, 250–251

This edition calls the shoes “walking boots”, but Meister Eckhart called them “schrittschuohe” in Middle High German. This is the ancestor of the German word for ice skates! The schritt- is from the Old High German scrītan, which can mean both stride and glide.

Does that mean Eckhart’s magic shoes are really ice skates? Stay tuned…

How to stop in 1772

“How do I stop?” is usually among the first questions asked by beginning skaters. Robert Jones notes that being able to stop is important because skaters often collide and recommends three ways to stop in his book (pp. 56–57):

Jump and make a quarter turn in the air

[Stopping] may be easily done, by leaping up, and coming down with the feet parallel, at about twelve inches asunder, and turned as much as possible to the right or left; so that according to the seaman’s phrase, the broad sides of the skates may be before you.

I have never seen anyone stop using this method. It sounds both showy and dangerous.

Hockey stop

When travelling, you may stop yourself, by only turning the feet to the right or left, as before described, and pressing on the inside edge of the foremost foot.

These first two methods are recommended and help skaters “avoid many dangers, such as banks of snow, broken ice, &c. “

Heel stop

This is the most common method, and the least useful.

But the method which skaters generally make use of to stop themselves, is by no means so certain; for as they only bear on the heels of their skates, they run a considerable distance before they stop, by which means they not only spoil the ice, but often break their skates; and, unless they perceive the danger at some distance, are not able to escape it.

This is an interesting parallel to inline skating today: skates designed for beginners typically come with a heel brake. It’s meant to be dragged on the ground to bring the skater to a gradual stop. This doesn’t work very well, and advanced skaters remove the heel brake (or buy skates without one) and stop in other ways.

Skating in Thomson’s Winter

James Thomson’s The Seasons was a collection of four poems, one for each season, published in the eighteenth century. Since this blog is about skating, we’re interested in Winter.

Winter was the first season to be published, in 1726. At that point it didn’t have any skating in it. That version is available from ECCO TCP.

The full collection was published in 1730. That version, available in Google books, does mention skating:

On blithesome frolicks bent, the youthful swains,

While every work of man is laid at rest,

Fond o’er the river rush, and shuddering view

The doubtful deeps below. Or where the lake

And long canal the cerule plain extend,

The city pours forth her thousands, swarming all,

From every quarter: and, with him who slides;

Or sketing [sic] sweeps, swift as the winds, along,

In circling poise; or else disorder’d falls,

His feet, illuded, sprawling to the sky,

While the laugh rages round; from end to end,

Encreasing still, resounds the crowded scene.

Thomson, The Seasons (1730), lines 718–729

Skating is spelled “sketing” in the main text, but an erratum corrects it to “skating”. This is corrected, and the passage reprinted, in the 1735 edition.

In the 1744 edition, we finally get the version Jones quotes:

On blithsome Frolicks bent, the youthful Swains

While every Work of Man is laid at rest,

Fond o’er the River croud, in various Sport

And Revelry dissolv’d; where mixing glad,

Happiest of all the Train! the raptur’d Boy

Lashes the whirling Top. Or, where the Rhine

Branch’d out in many a long Canal extends,

From every Province swarming, void of Care,

Batavia rushes forth; and as they sweep,

On sounding Skates, a thousand different Ways,

In circling Poise, swift as the Winds, along,

The then gay Land is madden’d all to Joy.

Nor less the northern Courts, wide o’er the Snow,

Pour a new Pomp. Eager, on rapid Sleds,

Their vigorous Youth in bold Contention wheel

The long-resounding Course. Mean-time, to raise

The manly Strife, with highly-blooming Charms,

Flush’d by the Season, Scandinavia‘s Dames,

Or Russia‘s buxom Daughters glow around.

Thomson, The Works of James Thomson, vol. 1 (1750), Winter, lines 763–781. (Text matches the 1744 edition.)

In grad school I learned that all the interesting research questions in philology have already been answered by nineteenth-century German guys. This one is no exception. Otto Zippel wrote his dissertation on the textual history of Winter. The next year, he published a critical edition of the Seasons “together with all the various readings of the later editions” (1908, v). Skating first appears in his C text; the 1744 edition is his E text.

Cross-grinding example

I previously wrote about what cross-grinding is and why it’s not always bad. Here is a photo of one of my skates showing the distinctive marks left by cross-grinding.

Cross-grinding leaves many small lines perpendicular to the length of the blade.

If the cross-grinding wheel is too coarse (like the one I used with my Ferodowill skate holder), these can keep the blades from gliding nicely or worse, catch the ice and cause a fall. I discovered this when I took my Ferodowill-sharpened Jones skates out on the ice. As long as you smooth them out (e.g., by stoning the blade), they’re nothing to worry about.

Editions of Robert Jones’s Treatise on Skating

I’ve sorted out the various editions of Robert Jones’s Treatise on Skating in a new article. As I was doing this, I discovered several new things that aren’t mentioned in my edition of his book. It seemed like lots of new stuff has come online in the last few years! And now it’s time to update my edition.

This article was part of my contribution to the new skating bibliography on Schaatshistorie,nl. It is now live, but more items are still being added. I still have a stack of bone skates references to put in. It will be an amazing resource when it’s done.

Internet articles about the Xinjiang skates

This is just a list of links with some comments. It’s an interesting example of how a story spreads and grows despite a lack of reliable new information.

Here’s the press release from the Chinese Academy of Social Sciences by Zhou Ye (2/27/2023, in Chinese). It focuses on the non-skate finds and has roughly the same information as Kang’s article published the day before. See also my post about these skates, which is the only reference to my book that I’ve seen so far.
