This is a diagram of how a solar eclipse works, or at least how they thought one worked in the 14th century. It might be one of the very first illustrations of its kind. As explained by the book’s description in archive.org:
This book, which contains Sacro Bosco’s influential, 13th-century astronomy tract, along with works by Peurbach and Regiomontanus, is notable for its color illustrations. In particular, this edition, issued by Erhard Ratdolt in 1485, is considered to be the first …
The Malibu Painter, who probably painted this, was not active in California’s surf culture, but in Egypt around the time the first Christians started showing up. They were still making mummies, but they were part of the Roman Empire.
Archaeologists believe portraits like these were painted while the subjects were alive, displayed in their homes, then slipped into the wrappings of their mummified bodies after their death. They don’t know the name of the painters, but thin…

Science Art: Torpille Moderne/Torpille Ancienne from Dreadnought ou submersible by Olivier Guihéneuc, 1916
Two torpedoes, modern (as of 1916) and ancient. That’s about the limit of my French. The book is about naval warfare, and was published while World War I was going on, and at a time when submarines were still kind of science-fictiony. Actually, they still kind of are, aren’t they?
I guess these torpedoes are how a submersible would attack a dreadnought.
Dreadnought ou Submersible is available to read on archive.org, if your French is better than mine.
This is a fairly speculative reconstruction of an elephant-relative we really only know from footprints (or so says Wikimedia Commons, who are probably on the money here). The ears, lips and trunk might be off. Or they might not be. There were other critters who we know looked a lot like this, a few thousand millennia ago.
Nowadays, we call this a deinotherium (with the “e”) and we think it looked more like this.
This painting was part of a set of trading cards made …
