why did zeus turned io into a cow
Io (mythology) Io was a priestess of the Goddess Hera in Argos,[5][16] whose cult her father Inachus was supposed to have introduced to Argos.[5] Zeus noticed Io, a mortal woman, and lusted after her. In the version of the myth told in Prometheus Bound she initially rejected Zeus' advances, until her father threw her out of his house on the advice of oracles.[17] According to some stories, Zeus then turned Io into a heifer in order to hide her from his wife;[5] others maintain that Hera herself transformed Io.[17][18]
Percy Jackson: Sea of Monsters While in Camp Half-Blood, Percy recounts the story of Thalia and her sacrifice. A young Annabeth, Luke, Grover and Thalia are running to Camp Half-Blood while being pursued by monsters. Thalia sacrifices herself to get the others into the camp, and her father Zeus turns her into a tree which forms a barrier around it.The campers realize that Thalia's tree has been poisoned by Luke and they are vulnerable to attacks. Percy visits the Oracle, who tells him of a prophecy of a half-blood of the eldest gods either saving or destroying Olympus. Chiron tells Percy that he is the only living, human half-blood of the eldest gods, so the half-blood in the Prophecy may refer to him. Annabeth and Grover learn about the Golden Fleece, which has the power to heal anything, and propose a quest in which they retrieve the Fleece and use it to heal Thalia's tree. Mr. D chooses Clarisse to lead the quest, much to Annabeth's and Percy's dismay. Percy convinces Grover and Annabeth to accompany him on the quest, and Tyson joins them. Annabeth hails the Chariot of Damnation, and Percy threatens the three drivers (the Graeae) to tell him of his prophecy, giving him coordinates for the Sea of Monsters (the Bermuda Triangle) before ejecting the group from the cab in Washington D.C. because they lack money. While walking down the street, Grover is kidnapped by Chris Rodriguez and taken to Luke. Percy, Annabeth, and Tyson first locate Luke with the help of Hermes, then ride a Hippokampos to his yacht, the Andromeda. Luke reveals his plan to revive Kronos using the Fleece so Olympus will be destroyed. Percy and they are then locked in the brig, though they later escape when Percy uses his ability to manipulate water.
