Poseidon (Neptune) was the Sea God and next in power to Zeus. He was the father of the giant Polyphemus whom Ulysses blinded, and is the consistent enemy of Ulysses throughout the whole Odyssey. Neptune was the brother of Zeus.
Hermes (Mercury) was the messenger of the gods and a son of Zeus. He was especially the patron of travellers and well disposed to Ulysses.
Tiresias was in life a celebrated soothsayer and philosopher of Thebes. His wisdom was universal. Having inadvertently seen the Goddess Athene bathing in the fountain of Hippocrene, he was blinded. Ulysses visited his spirit in Hades, in order to obtain his advice as to the journey homewards to Ithaca.
Circe. An enchantress celebrated for her knowledge of the magic properties of herbs. She was of extreme personal beauty. In girlhood she married the prince of Colchis, whom she murdered to obtain his kingdom. She was thereon banished to the fairy island of Ææa. When Ulysses visited her shores she changed his companions into swine, but Ulysses was protected by the magic virtues of a herb called moly. Ulysses spent a year in the arms of Circe, and she gave birth to a son called Telegonus.
Calypso. One of the daughters of Atlas, was known as the “bright-haired Goddess of Silence,” and was queen of the lost island of Ogygia. Ulysses spent seven years with her, and she bore him two sons. By order of Zeus, Hermes was sent to the island ordering Ulysses to leave his voluptuous sloth, and Calypso, who was inconsolable at his loss, was forced to allow him to depart. The legend runs that the goddess offered him the gift of immortality if he would remain with her.
Scylla and Charybdis. Scylla was a terrible female monster who devoured six of Ulysses’ crew, though the hero himself escaped her. Below the waist she was composed of creatures like dogs who never ceased barking. She was supported by twelve feet and had six different heads. The monster dwelt in a cave under the sea on one side of a narrow strait off the coast of Sicily. On the other side of the strait was the great whirlpool Charybdis. It was invested with a personality by Homer, and Charybdis was said to be a giantess who sucked down ships as they passed.
The Sirens. Monsters with sweet alluring voices who inhabited a small island near Sicily. They had bodies like great birds, according to some writers, with the heads of beautiful women. Whosoever heard their magic song must go to them and remain with them for ever. Ulysses escaped the enchantment by causing himself to be bound to the ship’s mast.
Polyphemus. The son of Poseidon. He was the giant king of the Cyclopes who were workers in the forge of Vulcan and made armour for the gods. Ulysses and his companions blinded him in order to escape from the cavern where he had imprisoned them.
Antinous. A native gentleman of Ithaca, one of Penelope’s most persistent suitors. When Ulysses came home disguised as a beggar Antinous struck him. He was the first to fall by Ulysses’ bow.
Euryclea. The nurse of Ulysses in his infancy, and one of the first to recognise him on his return from his wanderings. She was in her youth the lovely daughter of Ops of Ithaca.
