Greaves and Vambraces in the rank and file

[Tarbicus]

I think Imperial greaves are mostly associated with Late Roman and Dacia, and as most re-enactment is 1st-C AD then it kinda makes sense they wouldn't be seen much. There is good reason to suppose they weren't in use much in the 1st-C AD I guess, but some (including me) don't see why they would suddenly disappear then reappear.

I can't say I've ever seen vambraces in sculpture, even though I've thought a couple of maybes.
