As a mostly agriculture-based society, the Inca worshipped what was important to them. They worshipped Inti the Sun-God who provided sunlight and enlightenment. Mama Quilla the Moon-god who provided the seasons, protection from the dark, and was a protector of women. The third God would be the essential piece missing for an agricultural society to thrive and that God’s name was Illapa, Master of Clouds Rain and Hail.
The Inca believed that when it rained it was because a jug of water had been spilled from a broken water jug high in the sky. This water jug contained water from the Milk Way Galaxy.
