Reportedly, in November1599 a Jesuit named Alonzo Ruiz had announced in Arequipa that divine punishment would strike the natives for continuing to worship their gods and the Spaniards for promiscuity. Mythology held that before the 1600 eruption the lack of sacrifices had upset the devil. It sent a large snake named or to announce "horrifying storms" which eventually ended up killing the natives. Jesuits interpreted this as a deception attempt by the devil. Such prophecies may reflect prior knowledge about the volcanic nature of Huaynaputina. There are reports that a sacrificial offering was underway at the volcano a few days before the eruption.
