Histories

So when Adrastus had answered Croesus thus, they went out provided with chosen young men and dogs. When they came to Olympus (mountain), Nomos Larisis, Thessaly, Greece, Europe Mount Olympus, they hunted for the beast and, finding him, formed a circle and threw their spears at him:

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.
