King prays for white bull, as a sign that he has Poseidon's approval to become king instead of one of his brothers.
The bull appears, but the new King refuses to sacrifice it to Poseidon because it's so beautiful.
Aphrodite, to punish the King, casts a spell that makes the Queen fall in love with the bull. The Queen is so in love, that she crawls inside a specially made hollow cow so she can get 'busy" with the bull.
The Minotaur is the result of the mating.
The Aristocrats!
