When Salvador Dali set out to paint a depiction of the infamous Roman Emperor Caligula in 1971, he chose to depict the thing nearest and dearest to the emperor's heart: his favorite racehorse, Incitatus. The painting “Le Cheval de Caligula” shows the pampered pony in all his royal glory. It is wearing a bejeweled crown and clothed in purple blankets and a collar of precious stones. While the gaudy clothing of the horse is historically correct, the Spanish surrealist artist managed perhaps for the only time to understate the strangeness of his subject matter.

Gaius Julius Caesar Augustus Germanicus (Caligula) was born in 12 A.D. and reigned from 37-41. He was the first emperor with no memory of the pre-Augustan era, that is, before emperors were deified—and had no compunction about being worshipped as a god. As the object of a cultus, the boy emperor believed in his own semi-divine status and saw no reason not to follow whatever strange desire entered his mind, such as treating his horse better than royalty. The Roman historian Suetonius writes that he gave the horse eighteen servants, a marble stable, an ivory manger, and rich red robes. He demanded that it be fed oats mixed with flex of gold and wine delivered in fine goblets. Dignitaries bowed and tolerated Incitatus as a guest of honor at banquets. Caligula repeatedly mocked the system of imperial decorum in Roman upper crust society in incidents such as these. His actions led to his violent death at the hands of political rivals.
