Tlaloc was an Aztec god of rain, fertility and water. Considered as a war-freak and unsatisfied god, when he’s in a bad mood he would send drought and famine in the land. To appease him, the Aztec priests would sacrifice children from 8 years and below. They would either cut their fingers or pull their fingernails one by one to make them cry. Their cries were like music to Tlaloc’s ears. Also, the priests would try to collect their tears also to be sacrificed to him.
