myth states that Omate volcano (Huaynaputina) wanted the assistance of Arequipa volcano (probably El Misti) to destroy the Spaniards but the latter could not, claiming that he was Christian now, and so Huaynaputina proceeded alone. Another states that instead, Huaynaputina asked Machuputina (Misti) to deal with the Catholic Arequipa; when the latter refused as it too had become Catholic Huaynaputina exploded from anger. El Misti had erupted less than two centuries before, and local populations were further concerned that after Huaynaputina, El Misti might erupt next. As a result, natives and Franciscan friars threw sacrifices such as relics of saints into its crater. Shamans in the Tambo valley urged a return to old customs, and processions and sacrifices to Huaynaputina took place. In Arequipa, a new patron saint, San Genaro, was named following the eruption and veneration of Martha – who was believed to have power over earthquakes – increased; she became the city's sole patron saint in 1693. 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. Global atmospheric impacts of the 1600 eruption After the eruption, anomalies in the appearance of the sun were described in Europe and China as a "dimming" or "reddening" "haze" that reduced the sun's luminosity in a cloudless sky and reduced the visibility of shadows. Vivid sunsets and sunrises were noted. A darkened lunar eclipse described by observers in Graz, Austria, in 1601 may have been the consequence of the Huaynaputina aerosols. Acid layers in ice cores from Antarctica and Greenland have been attributed to Huaynaputina, and their discovery led to initial discussion about whether the 1600 eruption had major effects on Earth's climate. In Antarctica these ice cores include both acid layers and volcanic tephra. The total amount of sulfuric acid erupted by Huaynaputina has been estimated at several values: Other estimates are 50–100 million tons for the
