This she held so tight that the waters never even wet it; and it was only long after, when too late to remedy it, that an oracle told her that Achilles could be wounded in his heel, which the waters of the Styx had not touched. As soon as this good mother heard the first news of the coming war, her heart was troubled; for she knew that Achilles, who was now a young man, would want to join the army, and she was afraid of losing him.
To prevent his hearing anything about the war, she persuaded him to visit the King of Scyros. There, under pretext of a joke, he was induced to put on girl’s clothes, and to pretend that he was a woman.
The Greeks, after hearing the oracle’s words, sent messengers for Achilles; but they could not find him, as he had left home, and no one would tell them where he had gone. As it was of no use to set out without him, according to the oracle’s answer, which they thoroughly believed, the army lingered at Aulis in despair.
Ulysses, seeing that they would never start unless Achilles were found, now offered to go and get him. Disguised as a peddler, with a pack upon his back, he went first to Achilles’ home, where the chattering maids told him all he wished to know, and thence he went to the Island of Scyros.
Achilles was so well disguised that Ulysses could not tell him from the king’s daughters and their maids: so he made use of a trick to find him out. Among the trinkets in his pack, he put a sword of fine workmanship, and, entering the palace, spread out his wares before the admiring maidens. They all gathered about him; but, while the real girls went into raptures over his ornaments, Achilles grasped the sword, drew it from the scabbard, carefully tested the blade, and swung it with a strong arm.
