what mortal would not want to bed a goddess and sire a son from her? Divine blood purified our muddy race, bred heroes from dust and clay. And this goddess brought a greater promise still: the Fates had foretold that her son would far surpass his father. Peleus’ line would be assured. But, like all the gods’ gifts, there was an edge to it; the goddess herself was unwilling. Everyone, even I, had heard the story of Thetis’ ravishment. The gods had led Peleus to the secret place where she liked to sit upon the beach. They had warned him not to waste time with overtures—she would never consent to marriage with a mortal. They warned him too of what would come once he had caught her: for the nymph Thetis was wily, like her father, Proteus, the slippery old man of the sea, and she knew how to make her skin flow into a thousand different shapes of fur and feather and flesh. And though beaks and claws and teeth and coils and stinging tails would flay him, still Peleus must not let her go. Peleus was a pious and obedient man and did all that the gods had instructed him to do. He waited for her to emerge from the slate-colored waves, hair black and long as a horse’s tail. Then he seized her, holding on despite her violent struggles, squeezing until they were both exhausted, breathless and sand- scraped. The blood from the wounds she had given him mixed with the smears of lost maidenhead on her thighs. Her resistance mattered no longer: a deflowering was as binding as marriage vows. The gods forced her to swear that she would stay with her mortal husband for at least a year, and she served her time on earth as the duty it was, silent, unresponsive, and sullen. Now when he clasped her, she did not bother to writhe and twist in protest. Instead she lay stiff and silent, damp and chilled as an old fish. Her reluctant womb bore only a single child. The hour her sentence was finished, she ran out of the house and dove back into the sea. She would return only to visit the boy, never for any other reason, and never for long. The rest of the time the child was raised by tutors and nurses and overseen by Phoinix, Peleus’ most trusted counselor. Did Peleus ever regret the gods’ gift to him? An ordinary wife would have counted herself lucky to find a husband with Peleus’ mildness, his smile-lined face. But for the sea-nymph Thetis nothing could ever eclipse the stain of his dirty, mortal mediocrity. I WAS LED through the palace by a servant whose name I had not caught. Perhaps he had not said it. The halls were smaller than at home, as if restrained by the modesty of the kingdom they governed. The walls and floors were local marble,
