Maia (; Ancient Greek: Μαῖα; also spelled Maie, ; ), in ancient Greek religion and mythology, is one of the Pleiades and the mother of Hermes, one of the major Greek gods, by Zeus, the king of Olympus. Family Maia is the daughter of Atlas and Pleione the Oceanid, and is the oldest of the seven Pleiades. They were born on Mount Cyllene in Arcadia, and are sometimes called mountain nymphs, oreads; Simonides of Ceos sang of "mountain Maia" (Maiados oureias) "of the lovely black eyes." Because they were daughters of Atlas, they were also called the Atlantides. Mythology Birth of Hermes According to the Homeric Hymn to Hermes, Zeus, in the dead of night, secretly made love to Maia, who avoided the company of the gods, in a cave of Cyllene. She became pregnant with Hermes. After giving birth to the baby, Maia wrapped him in blankets and went to sleep. The rapidly maturing infant Hermes crawled away to Thessaly, where by nightfall of his first day he stole some of his half-brother Apollo's cattle and invented the lyre from a tortoise shell. Maia refused to believe Apollo when he claimed that Hermes was the thief, and Zeus then sided with Apollo. Finally, Apollo exchanged the cattle for the lyre, which became one of his identifying attributes. Although the Homeric Hymn has Maia as Hermes' caretaker and guardian, in Sophocles's now lost satyr play Ichneutae, Maia entrusted the infant Hermes to Cyllene (the local mountain goddess) to nurse and raise, and thus it is her that the satyrs and Apollo confront when looking for the god's missing cattle. As nurturer Maia also raised the infant Arcas, the child of Callisto with Zeus. Wronged by the love affair, Zeus' wife Hera in a jealous rage had transformed Callisto into a bear. Arcas is the eponym of Arcadia, where Maia was born. The story of Callisto and Arcas, like that of the Pleiades, is an aition for a stellar formation, the constellations Ursa Major and Ursa Minor, the Great and Little Bear. Her name is related to μαῖα (maia), an honorific term for older women related to μήτηρ (mētēr) 'mother', also meaning "midwife" in Greek. Roman Maia In ancient Roman religion and myth, Maia embodied the concept of growth, as her name was thought to be related to the comparative adjective maius, maior "larger, greater".
