Little is known of Gaius Julius Hyginus’s (GAY-uhs JEWL-yuhs huh-JI-nuhs) life. He is usually called a Spaniard, but some authorities say he was born in Alexandria. He is not to be confused with the second century surveyor Hyginus, Saint Hyginus, pope from c. 136 to c. 140 c.e., or Hyginus the mythographer, author of Genealogiae (also known as Fabulae, probably second century c.e.). Brought to Rome as either a slave or a prisoner of war, he was freed by the emperor Augustus. In Rome, he may have studied under Lucius Cornelius Alexander Polyhistor. He was first the teacher and later the friend of Ovid. Augustus placed Hyginus in charge of the greater of the two public libraries he founded, the Palatine Library. Hyginus wrote much and was widely respected as an author, a critic, and an editor, but none of his works survives.
