BTW, Mary Shelley is the author of Frankenstein <span />
Is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still read by contemporary audiences. As with the Iliad, the poem is divided into 24 books. It follows the Greek hero Odysseus, king of Ithaca, and his journey home after the Trojan War. After the war itself, which lasted ten years, his journey lasts for ten additional years, during which time he encounters many perils and all his crewmates are killed. In his absence, Odysseus is assumed dead, and his wife Penelope and son Telemachus must contend with a group of unruly suitors who compete for Penelope's hand in marriage.
