But Dêlos was not an oracular spot: Apollo did not manifest himself there as revealer of the futurities of Zeus. A place must be found where this beneficent function, without which mankind would perish under the innumerable doubts and perplexities of life, may be exercised and rendered available. Apollo himself descends from Olympus to make choice of a suitable site: the hymnographer knows a thousand other adventures of the god which he might sing, but he prefers this memorable incident, the charter and patent of consecration for the Delphian temple. Many different places did Apollo inspect; he surveyed the country of the Magnêtes and the Perrhæbians, came to Iôlkos, and passed over from thence to Eubœa and the plain of Lelanton. But even this fertile spot did not please him: he crossed the Euripus to Bœotia, passed by Teumêssus and Mykalêssus, and the then inaccessible and unoccupied forest on which the city of Thêbes afterwards stood. He next proceeded to Onchêstos, but the grove of Poseidôn was already established there; next across the Kêphissus to Okalea, Haliartus, and the agreeable plain and much-frequented fountain of Delphusa, or Tilphusa. Pleased with the place, Apollo prepared to establish his oracle there, but Tilphusa was proud of the beauty of her own site, and did not choose that her glory should be eclipsed by that of the god.[101] She alarmed him with the apprehension that the chariots which contended in her plain, and the horses and mules which watered at her fountain would disturb the solemnity of his oracle; and she thus induced him to proceed onward to the southern side of Parnassus, overhanging the harbor of Krissa. Here he established his oracle, in the mountainous site not frequented by chariots and horses, and near to a fountain, which however was guarded by a vast and terrific serpent, once the nurse of the monster Typhaôn. This serpent Apollo slew with an arrow, and suffered its body to rot in the sun: hence the name of the place, Pythô,[102] and the surname of the Pythian Apollo. The plan of his temple being marked out, it was built by Trophônios and Agamêdês, aided by a crowd of forward auxiliaries from the neighborhood. He now discovered with indignation, however, that Tilphusa had cheated him, and went back with swift step to resent it. “Thou shalt not thus,” he said, “succeed in thy fraud and retain thy beautiful water; the glory of the place shall be mine, and not thine alone.” Thus saying, he tumbled down a crag upon the fountain, and obstructed her limpid current: establishing an altar for himself in a grove hard by near another spring, where men still worship him as Apollo Tilphusios, because of his severe vengeance upon the once beautiful Tilphusa.[103] [101] Hom.
