70v - Clothing

[Rafal]

Maybe the original artist drew them naked first, then got an attack of prudery and dressed them

I think it is just the opposite. Notice that dressed nymphs appear only at Aries and Taurus pages (f71r, f71v). These pages have their duplicates with naked nymphs (f72r1, f72r2). Surprisingly the new versions contain totally different text (which could be an argument that the text is some random, meaningless crap).

The rest of pages contain naked nymphs.

I feel that the illustrator first drew the clothed version, maybe only one sheet. Then he changed his mind and switched to naked version. He redid this one sheet and did all the rest naked.
