“Phylarkhos claims that Thetis went to Hephaistos on Olympos so that he might create weapons for Achilles and that he did it. But, because Hephaistos was lusting after Thetis, he said he would not give them to her unless she had sex with him. She promised him that she would, but that she only wanted to try on the weapons first, so she could see if the gear he had made was fit for Achilles. She was actually the same size as him.
Once Hephaistos agreed on this, Thetis armed herself and fled. Because he was incapable of grabbing her, he took a hammer and hit Thetis in the ankle. Injured in this way, she went to Thessaly and healed in the city that is called Thetideion after her.”
“Peleus’ knife”: this is a proverb. Aristophanes also records this: “he thinks more of himself than Peleus did with the knife”. It seems that this thing which Peleus took was a Hephaistos-made gift of prudence.”
