Incitatus
Incitatus was Roman emperor Caligula's favored horse. Some have indicated that the horse was attended to by eighteen servants, and was fed oats mixed with gold flake; according to Suetonius's Lives of the Twelve Caesars, Incitatus had a stable of marble, with an ivory manger, purple blankets, and a collar of precious stones. Suetonius also wrote that Caligula planned to make Incitatus a consul. Caligula even procured him a wife, a mare named Penelope. It has also been said Caligula claimed his horse to be a 'combination of all the gods' and to be worshipped as such.
Caligula was a crazy insane BITCH
The horse would also "invite" dignitaries to dine with him, and had a house with full complement of servants to entertain such guests.
Historical revisionists like Anthony A. Barrett in Caligula: The Corruption of Power (Yale, 1990) question the negative portrait of Caligula. They ascribe Caligula's treatment of Incitatus as a way of ridiculing and angering the Senate, rather than a proof of his insanity. They suggest that later historians like Suetonius and Dio Cassius were motivated by the politics of their times and that their histories were distorted by the desire to include more colorful, but perhaps less reliable sources.
The word "Incitatus" is a Latin adjective, which in English would be translated as "Galloper."
Incitatus appears as a fable character in issue 22 of the comic Jack of Fables.
