The myth of King Minos

Minos was a son of Zeus and became the great king of Crete, giving name to the Minoan culture. He had many splendid palaces and a huge fleet that dominated the Aegean Sea for many years. Among the things he did, he dispelled his brother Rhadamnthys from the island, who died soon and went to the land of Hades as a judge.
   One day, the sea God Poseidon asked Minos for something more than a regular prayer. He wanted him to make a sacrifice, exactly a white bull. The bull is the coat of arms of Crete, since Zeus was transformed into a bull, and the palaces were completely decorated with horns of bulls. But, where could he find a white bull…? there is not such a thing in Crete. When he told this to Poseidon, the God sent him a white bull from out of the sea. 
  When Minos found the bull, he liked it so much that he wanted it for himself. Then he though that instead of sacrificing the white one to Poseidon, he could kill an ill bull from his land and keep the white one. So he did. But naturally Poseidon could the trick and took revenge in his own way.
