Aristeas was a semi-legendary Greek poet and miracle-worker, a native of Proconnesus in Asia Minor, active ca. 7th century BCE. In book IV of The History, Herodotus reports that Aristeas appeared to drop down dead in a fuller's shop, but before his relatives could collect the body, disappeared, only to return six years later.
Aristeas was supposed to have authored a poem called the Arimaspea, giving an account of travels in the far North. There he encountered a tribe called the Issedones, who told him of still more fantastic and northerly peoples: the one-eyed Arimaspi who battle gold-guarding gryphons, and the Hyperboreans among whom Apollo lives during the winter.
Two hundred and forty years after his death, Aristeas appeared in Metapontum in Southern Italy to command that a statue of himself be set up and a new altar dedicated to Apollo, saying that since his death he had been travelling with Apollo in the form of a sacred raven.
