Agrigentum—until 405 B.C., when it was destroyed by the Carthaginians—was famous for its horses. It is said that on one occasion, when one of the best-known citizens, Exænetus, won the principal chariot race at Olympus, the entire population came forth to meet him, and that he was preceded into the city by 300 chariots drawn by pairs of white horses. Indeed some of the most gorgeous monuments ever erected to the memory of famous race horses were those raised in this city during the period of its splendour. [Illustration: 1. THE EMPEROR TRAJAN.

Yet in common with the people of many other races they were addicted to immolating horses on festival days, while the practices in which they indulged upon these occasions are said to have been barbarous in the extreme. In almost every age white horses in particular would seem to have been used for sacrificial purposes. The Persians sacrificed bulls as well as horses, a bull and a horse being sometimes bound together and then immolated. Arrian mentions that one horse at least was sacrificed to Cyrus every month, the ceremony being usually performed at Pasargadea, close to the famous tomb. Here again white horses were used for the sacrifices, for among the Persians in particular the white horse was for many centuries deemed sacred and pronounced “beloved of the gods.” One of the descriptions that probably gives a true account of a triumphal march in the third century B.C. is that of Herodotus, where he describes the procession of Xerxes. The following order, he tells us, was observed. There came first 1000 carefully selected horsemen, then 1000 carefully selected spearsmen, then ten sacred Nisæan horses “splendidly caparisoned.” These horses were called Nisæan, we are incidentally told, because they were especially reared on the plains of Nisæa, in Media, at that period famous for its great horses. Next came the sacred car of Zeus, drawn by eight white horses “followed by charioteers on foot holding their bridles, for no mortal was allowed to mount the seat.” Xerxes himself brought up the train, usually in a chariot drawn by Nisæan horses, with his charioteer beside him. * * * * *
