The King of Crete, Minos, gave Heracles permission to take the bull away. It had been wrecking havoc on Crete. Heracles used a lasso and rode it back to his cousin, Eurystheus. Eurystheus wanted to sacrifice bull to Hera, who hated Heracles. She refused the sacrifice because it reflected glory on Heracles. The bull was released and wandered to Marathon, becoming known as the Marathonian Bull.
