Another new Graham Sumner book?

[jho]

I would interpret the leggings as a clumsy attempt to show normal pteryges.

Compare this gravestone of Caius Valerius Secundus from Mainz:

Actually, when I revisited the drawing of Caius Valerius Crispus in the image base just now, it appears that the pteryges continue between the legs:

I have never noticed this on the original and therefore it may be an issue of over-interpretation by the artist but in any event it appears reasonable to assume that in both cases normal pteryges are intended.
