Quetzalcóatl

Traditionally the god of the morning and evening star, he later became known as the patron of priests, inventor of books and of the calendar, and as the symbol of death and resurrection. His worship involved human sacrifice. Legend said that he would return in another age, and when Montezuma, last king of the Aztecs, received news of the landing of Cortés and his men in 1519, he thought that Quetzalcóatl had returned
