Apollodorus Library 3.1.4

[4] But angry at him for not sacrificing the bull, Poseidon made the animal savage, and contrived that Pasiphae should conceive a passion for it. ¹ In her love for the bull she found an accomplice in Daedalus, an architect, who had been banished from Athens for murder. ² He constructed a wooden cow on wheels, took it, hollowed it out in the inside, sewed it up in the hide of a cow which he had skinned, and set it in the meadow in which the bull used to graze. Then he introduced Pasiphae into it; and the bull came and coupled with it, as if it were a real cow. And she gave birth to Asterius, who was called the Minotaur. He had the face of a bull, but the rest of him was human; and Minos, in compliance with certain oracles, shut him up and guarded him in the Labyrinth. Now the Labyrinth which Daedalus constructed was a chamber “ that with its tangled windings perplexed the outward way. ” ³ The story of the Minotaur, and Androgeus, and Phaedra, and Ariadne, I will tell hereafter in my account of Theseus. ⁴
