Cannons versus Pipes

[Koen G]

Some interesting imagery from the Rosenwald5+6 mentioned above
These are copies of Vegetius' De rei militari and one of the sources for Taccola's works.

Very interesting, thanks! These particular manuscripts were copied after Taccola's death, but it does seem clear that he had a version of this, which influenced some of his choices.

What stood out to me in the images you posted is the scallop patterns around what I assume to be joints in the metal (?). I don't know if these are purely decorative, a result of the working process, or something reinterpreted by the copyist. I don't remember seeing something like it in Taccola.
