was not deified although the Orion figure was probably Commodos from the film. My same history book is less clear as to weather or not Commodus was deified. They say "No(?)". I think that the gladatorial games were orginally part of a funeral right.
Indeed they were. It was later when they turned into entertainment but their origins were in the Etruscan funeral rituals.
...but I think we c(sh)ouldn't count all those later gladiator figures as religious figures.
