Hi Michael,
The ones you just showed look much more familiar. Now I know where the modern reconstructionists are using to make those trebuchets and siege equipment. They need to make one of those assault dragons, though.
As an aside, people are still reprinting Roman works with new pictures. As a child, I was given one that had some of Pliny's
Naturalis historia (in latin) with fanciful pictures attached. They'd picked Pliny's more colorful mistakes to illustrate, of course. Even under modern law, the old texts are in the public domain, so someone could take Flavius Vegetius Renatus and illustrate it as they liked.
Project for someone here, perhaps, without herbal inspiration?
