On Crete the Minoan Culture started 4700 years ago. The palace of Knossos is well-known and is a labyrinth. Visitors were lost in the labyrinth unless they used a string behind them to find their way back. In this place, it was said that a Minotaur, half bull and half man, lived. Every year seven young men and seven girls were sacrificed to the Minotaur. Many scholars think sacrifices to a bull were made because the Cretans thought the sound of an earthquake was an angry bull.
