Dacian helmets depicted as trophies.

[Hildebrandt]

I keep coming across old copper plate engravings of Dacian trophies from Roman monuments, but I am curious to see the original carvings that they are based on. These 18th C engravings are supposedly composite images of elements taken from the cubic base of Trajan's Column. Does anyone have or know where I can find photos of the relevant sculpture?




Thanks!
