(M217) At Thebes a festival called the Laurel-bearing was held once in every eight years, when branches of laurel were carried in procession to the temple of Apollo. The principal part in the procession was taken by a boy who held a laurel bough and bore the title of the Laurel-bearer: he seems to have personated the god himself. His hair hung down on his shoulders, and he wore a golden crown, a bright-coloured robe, and shoes of a special shape: both his parents must be alive.(621) We may suppose that the golden crown which he wore was fashioned in the shape of laurel leaves and replaced a wreath of real laurel. Thus the boy with the laurel wreath on his head and the laurel bough in his hand would resemble the traditional equipment of Apollo when he purified himself for the slaughter of the dragon. We may conjecture that at Thebes the Laurel-bearer originally personated not Apollo but the local hero Cadmus, who slew the dragon and had like Apollo to purify himself for the slaughter. The conjecture is confirmed by vase-paintings which represent Cadmus crowned with laurel preparing to attack the dragon or actually in combat with the monster, while goddesses bend over him holding out wreaths of laurel as the meed of victory.(622) On this hypothesis the octennial Delphic Festival of Crowning and the octennial Theban Festival of Laurel-bearing were closely akin: in both the prominent part played by the laurel was purificatory or expiatory.(623) Thus at Olympia, Delphi, and Thebes a boy whose parents were both alive was entrusted with the duty of cutting or wearing a sacred wreath at a great festival which recurred at intervals of several years.(624)
