There is a vaulted entrance to the stadium about a hundred feet high (one of the oldest examples of such work in cut stone, 350-300 B.C.), through which none could pass but the judges and heralds, and the competitors, who must have gone through ten months’ training, and were lodged during the games at the public expense. Close to this entrance are still to be seen a large number of pedestals, on which stood at one time certain brazen images, well fitted to warn competitors against any infringement of the rules. They were called Zanēs in honour of Zeus, and they had all been placed there at the expense of persons who had been convicted of some violation of the rules. Giving or receiving bribes was the most common offence at Olympia, as it was indeed with the Greeks generally, even in the more serious game of politics. But there were others of a different nature. For example, Pausanias tells of a man of Alexandria who had come too late for the boxing match, and, finding that another had been adjudged the prize without a contest and was already wearing the olive wreath, put on the gloves as though for a fight and rushed at the victor, for which he was sentenced to pay a fine. In contrast to the penal erection of a statue to Zeus, the winner of a prize was allowed to put up a statue in commemoration of his victory, and the third time he thus distinguished himself he was at liberty to erect an image of himself. In this way Olympia became in course of time a great school of art as well as a gymnastic arena. In Homer there is no mention of statues of the gods, not even of wood, and the development of art in this line during the seventh and sixth centuries was very remarkable.
