What is "incitatus"

Incitatus was the favored horse of Roman emperor Caligula (reigned 37–41 AD). His name is a Latin adjective meaning "swift" or "at full gallop".

According to Suetonius, in the Lives of the Twelve Caesars (121 AD), Incitatus had a stable of marble, with an ivory manger, purple blankets, and a collar of precious stones. Dio Cassius has indicated that the horse was attended to by servants and was fed oats mixed with gold flake. Suetonius also wrote that it was said that Caligula planned to make Incitatus a consul, and that the horse would "invite" dignitaries to dine with him in a house outfitted with servants there to entertain such events.
