The order of the games in our day is to sacrifice victims to the god, and then to contend in the pentathlum and horse-race, according to the programme established in the 77th Olympiad, for before this horses and men contended on the same day. And at that period the pancratiasts did not appear till night for they could not compete sooner, so much time being taken up by the horse-races and pentathlum. And the Athenian Callias was the victor of the pancratiasts. But for the future they took care that neither the pentathlum nor horse-races should stand in the way of the pancratium. And as regards the umpires of the games, the original rules and those in vogue in our day are quite different, for Iphitus was the only umpire, and after Iphitus the posterity of Oxylus, but in the 50th Olympiad two men picked by lot out of all Elis were entrusted with the stewardship of the contests, and this practice of two umpires continued for a very long time. But in the 25th Olympiad afterwards 9 general Umpires were appointed: three for the horse-race, three to watch the pentathlum, and three to preside over the remaining games. And in the 2nd Olympiad after this a tenth Umpire was appointed. And in the 103rd Olympiad, as the people of Elis had 12 tribes, a general Umpire was appointed by each. And when they were hard pressed by the Arcadians in war, they lost a portion of their territory and all the villages in this portion, and so they were only 8 tribes in number in the 104th Olympiad, and had only 8 general Umpires accordingly. And in the 108th Olympiad they returned to the number of 10 general Umpires, and that has continued the number to our day. CHAPTER X. Many various wonders may one see, or hear of, in Greece: but the Eleusinian mysteries and Olympian games seem to exhibit more than anything else the divine purpose. And the sacred grove of Zeus they have from old time called Altis, slightly changing the Greek word for grove[69]: it is indeed called Altis also by Pindar, in the Ode he composed for a victor at Olympia. And the temple and statue of Zeus were built out of the spoils of Pisa, which the people of Elis razed to the ground, after quelling the revolt of Pisa and some of the neighbouring towns that revolted with Pisa. And that the statue of Zeus was the work of Phidias is shown by the inscription written at the base of it, “Phidias the Athenian, the son of Charmides, made me.” The temple is a Doric building, and outside it is a colonnade. And the temple is built of stone of the district. Its height up to the gable is 68 feet, its breadth 95 feet, and its length 230 feet. And its architect was Libon a native of Elis. And the tiles on the roof are not of baked earth, but Pentelican marble to imitate tiles. They say such roofs are the invention of a man of Naxos called Byzes, who made statues at Naxos with the inscription, “Euergus of Naxos made me, the son of Byzes, and descended from Leto, the first who made tiles of stone.”
