The Asclepius of the Juruna, an Indian tribe living along the Xingu River in Brazil. One day Uaica, out hunting in the forest, noticed a lot of dead animals under a large tree. When he approached the heap of beasts, he felt dizzy, fell down, and went to sleep. In his deep dream he saw Sinaa, the jaguar ancestor of the Juruna, who talked to him. This happened on several occasions till the deity told him to keep away.
Uaica obeyed. He also made a drink from the bark of the tree: from this potent brew he acquired many powers. Uaica became a great medicineman who could take away disease with the touch of his hand. Sinaa would come into his dreams again, and through their conversation all the needs of the people were supplied. Pressed by the Juruna, Uaica consented to marry, but his wife was unfaithful to him. Through this shortcoming and the attempt of her lover on Uaica's life the Juruna lost the medicine-man. It happened that Uaica, who had eyes in the back of his head, saw the swinging club, and instantly he disappeared into the hole it made on striking the ground. Uaica said: ‘I shall not return. Arrows and clubs will be your lot. I tried to teach what Sinaa wished, but now I go.’ Later the medicine-man is said to have beckoned the Juruna to follow him underground, but they were too baffled and frightened to do so.
