(M216) But the rites in which the children of living parents are required to officiate do not always aim at promoting the growth of the crops. At Olympia the olive-branches which formed the victors’ crowns had to be cut from a sacred tree with a golden sickle by a lad whose father and mother must be both alive.(618) The tree was a wild olive growing within the holy precinct, at the west end of the temple of Zeus. It bore the name of the Olive of the Fair Crown, and near it was an altar to the Nymphs of the Fair Crowns.(619) At Delphi every eighth year a sacred drama or miracle-play was acted which drew crowds of spectators from all parts of Greece. It set forth the slaying of the Dragon by Apollo. The principal part was sustained by a lad, the son of living parents, who seems to have personated the god himself. In an open space the likeness of a lordly palace, erected for the occasion, represented the Dragon’s den. It was attacked and burned by the lad, aided by women who carried blazing torches. When the Dragon had received his deadly wound, the lad, still acting the part of the god, fled far away to be purged of the guilt of blood in the beautiful Vale of Tempe, where the Peneus flows in a deep wooded gorge between the snowy peaks of Olympus and Ossa, its smooth and silent tide shadowed by overhanging trees and tall white cliffs. In places these great crags rise abruptly from the stream and approach each other so near that only a narrow strip of sky is visible overhead; but where they recede a little, the meadows at their foot are verdant with evergreen shrubs, among which Apollo’s own laurel may still be seen. In antiquity the god himself, stained with the Dragon’s blood, is said to have come, a haggard footsore wayfarer, to this wild secluded glen and there plucked branches from one of the laurels that grew in its green thickets beside the rippling river. Some of them he used to twine a wreath for his brows, one of them he carried in his hand, doubtless in order that, guarded by the sacred plant, he might escape the hobgoblins which dogged his steps. So the boy, his human representative, did the same, and brought back to Delphi wreaths of laurel from the same tree to be awarded to the victors in the Pythian games. Hence the whole festival of the Slaying of the Dragon at Delphi went by the name of the Festival of Crowning.(620) From this it appears that at Delphi as well as at Olympia the boughs which were used to crown the victors had to be cut from a sacred tree by a boy whose parents must be both alive.
