Interesting thought.
Caligula employed bull fighting didn’t he?
I’m wondering if there was any association with the whole thing and the Minoans.
The bull-leaping of the Knossos frescoes fairly screams tthat, doesn’t it? :^)
OTOH, it could very well be rooted much deeper and closer than ancient Persia.
