The planet Mercury was important to the Mayas. They named the planet after a god called Piltzintecuhtli, meaning Prince. He was young and had hair that shone like the Sun. He was thought to be very changeable. Mercury always appears to be changing from a morning star to the evening star. The Prince always tried to become a king. He always failed. In the same way, Mercury appears to try to climb across the sky. It always fails, appearing only close to the horizon.
