Senes is racing for my allied team, the Reds, and he is Very Roman.
Methinks Jojo was deciding whether to enter as a Summerian or Babylonian. Since Summer predates the Empire of Babylon.

It is unlikely, alas, we will have any new candidates for the race so just palce your bets on 'Anonymous'!

P.S. the guy in Ben Hur who go mangled in the Circus was Marsala.
