Plutarch was a prominant literary figure of his time.
He wrote a learned monograph on the subject of Isis and
Osiris. Plutarch was also a biographer. He wrote Life of
Alexander, which has the king visited by a venerable
prophet in a dream. In his story he quotes a Homeric
reference to the island of Pharos, which was enough to
conbince Alexander that he had found the right site.
