during a war with Dyme, allowed the Pisatans to celebrate the games. Six Olympiads later the king of Pisa came to Olympia with an army and took charge. The story leaves the Pisatans in control from about Olympiads 30 to 51, but some time between Ols. 48 and 52 the Eleans defeated Pisa and destroyed it, and henceforth controlled the games. Such a story was manifestly a contrivance by the later priests of Elis to justify their control of the games through a prior claim. It is contradicted by all the evidence.[84] The antiquity of Olympia is known to us from the results of excavations and from its religious history. The latest excavations on the site have disclosed the remains of six prehistoric buildings with apsidal endings, below the geometric stratum, upon the site of what used to be considered the remnants of the great altar of Zeus.[85] Such an inference is borne out by many primitive features in the religious history of the sanctuary. The altar of Kronos on the hill to the north of the Altis was earlier than that of Zeus; an earth altar antedated that of Zeus, while a survival of the earlier worship of the powers of the underworld is seen in the custom, lasting through later centuries, of allowing only one woman, the priestess of Demeter Chamyne, to witness the games. We also know that the worship of the Pelasgian Hera antedated that of the Hellenic Zeus; her temple, the Heraion, is the most ancient of which the foundations still stand, a temple built of stone, wood, and sun-dried bricks, whose origin is to be referred to the tenth, if not to the eleventh, century B. C.[86] We have already remarked that the worship of the hero Pelops preceded that of the god Zeus.[87] All such indications attest the high antiquity of Olympia. That it is not mentioned in Homer, while Delphi and Dodona are, only proves that in the poet’s time it was still merely a local shrine. Not until the beginning of the sixth century B. C. did it attain the distinction, which it retained ever afterwards, of being the foremost national festival of Hellas.[88]
