Maia

← Encyclopedia

Maia is a figure who carries two distinct lives under one name: in Greek myth she is the eldest of the Pleiades and the mother of Hermes, and in Roman cult she is an old Italic goddess of growth whom the Romans, in time, identified with her Greek namesake.

The Greek Maia is the daughter of the Titan Atlas and the Oceanid Pleione, one of the seven sisters set in the sky as the Pleiades. She is the quietest of them in the literature — a nymph who kept to a cave on Mount Cyllene in Arcadia rather than to the company of gods. There Zeus came to her in secret, and she bore Hermes. The early Homeric Hymn to Hermes tells the rest with relish: the child slips from his cradle the day he is born, steals the cattle of Apollo, invents the lyre from a tortoise shell, and talks his way out of the theft — a god of cunning, exchange, and crossings, born of a mother who asked for none of it. Some accounts add that Maia raised Arcas, the son of Callisto, after his mother was turned into a bear, which folds her into the older Arcadian cycle of the region.

The Roman Maia is a separate inheritance. She was an indigenous goddess of the earth’s increase and the warmth of spring, paired in cult with Vulcan and honoured on the first of May; Roman antiquarians derived the month’s name from hers, though the etymology was already contested in antiquity. Her name lies close to the everyday Greek and Latin word maia, a respectful term for an older woman, a nurse or midwife — “good mother.” That maternal sense ran through both figures and made the identification natural: when Rome equated its own Mercury with the Greek Hermes, the Mercury who was Maia’s son drew the Italic Maia toward the mother of Hermes, and the two were read as one. Ancient sources themselves were unsure how far the join should go, and at points entangled her further with Bona Dea and Fauna.

What scholarship establishes here is mostly the shape of a merger: two goddesses of different origin, brought together by a shared name and a shared association with nurture, in the long Roman work of fitting Greek myth onto native Italian cult. The literary Maia stays in the background of her son’s story — present at his birth, named in his genealogy, and then largely silent. The cultic Maia belonged to the calendar rather than to narrative, addressed in rite more than told in tale. The name held the two together, and the spring month still carries it.
