then the guest called Adrastus, the man who had been cleansed of the deed of blood, missed the boar with his spear and hit the son of Croesus.
So Atys was struck by the spear and fulfilled the prophecy of the dream. One ran to tell Croesus what had happened, and coming to Sardis [28.0167,38.475] (Perseus) Sardis told the king of the fight and the fate of his son.
Distraught by the death of his son, Croesus cried out the more vehemently because the killer was one whom he himself had cleansed of blood,
and in his great and terrible grief at this mischance he called on Zeus by three names—Zeus the Purifier, Zeus of the Hearth, Zeus of Comrades: the first, because he wanted the god to know what evil his guest had done him; the second, because he had received the guest into his house and thus unwittingly entertained the murderer of his son; and the third, because he had found his worst enemy in the man whom he had sent as a protector.
Soon the Lydians came, bearing the corpse, with the murderer following after. He then came and stood before the body and gave himself up to Croesus, holding out his hands and telling him to kill him over the corpse, mentioning his former misfortune, and that on top of that he had destroyed the one who purified him, and that he was not fit to live.
