Others say it was Roma, a daughter of the Trojan woman I have mentioned, who was wedded to Latinus the son of Telemachus and bore him Romulus; others that Aemilia, the daughter of Aeneas and Lavinia, bore him to Mars; and others still rehearse what is altogether fabulous concerning his origin. For instance, they say that Tarchetius, king of the Albans, who was most lawless and cruel, was visited with a strange phantom in his house, namely, a phallus rising out of the hearth and remaining there many days.
Now there was an oracle of Tethys in Tuscany, from which there was brought to Tarchetius a response that a virgin must have intercourse with this phantom, and she should bear a son most illustrious for his valour, and of surpassing good fortune and strength. Tarchetius, accordingly, told the prophecy to one of his daughters, and bade her consort with the phantom; but she disdained to do so, and sent a handmaid in to it.
When Tarchetius learned of this, he was wroth, and seized both the maidens, purposing to put them to death. But the goddess Hestia appeared to him in his sleep and forbade him the murder. He therefore imposed upon the maidens the weaving of a certain web in their imprisonment, assuring them that when they had finished the weaving of it, they should then be given in marriage. By day, then, these maidens wove, but by night other maidens, at the command of Tarchetius, unravelled their web. And when the handmaid became the mother of twin children by the phantom, Tarchetius gave them to a certain Teratius with orders to destroy them.
