Homeric Hymn 4 to Hermes 1 ff (trans. Evelyn-White): "Hermes, the son of Zeus and Maia . . . whom Maia bare, the rich-tressed nymphe, when she was joined
in love with Zeus,--a shy goddess, for she avoided the company of the blessed gods, and lived within a deep, shady
cave. There the Son of Kronos used to lie with the rich-tressed nymphe, unseen by deathless gods and mortal men, at
dead of night that sleep might hold white-armed Hera fast. And when the purpose of great Zeus was fulfilled, and the
tenth moon with her was fixed in heaven, she was delivered and a notable thing was come to pass. For then she bare a son, of many shifts."
Convallaria majalis is, as the name suggests, a May plant and thus has been often associated to the Roman goddess Maia, the oldest of the Seven Pleiades and bringer of plentitude, spring, growth (cfr. MAIESTAS and the IE *ma-/*mag-). She was especially honoured during the festivity of Floralia, starting from the 28th of April and ending on the 3rd of May, this transition being also the tangible Manifestation of what was in potential, the seed that brings to complete fructification, for She is the One that presides over the two months (incipis Aprili, transis in tempora Maii - Ov., Fast.). According to a Greek interpretation, she is also the mother of Hermes/Mercurius, "Intellect mediator of the Mvndvs, Axis Cieli that descends from the Sky/Ivpiter to the Earth/Maia. He is emblem of the Dawn of Sapientia, the Divine Child that is born, Messenger of the Gods, acting Verbum". And of course, god of magic and hidden knowledge. The plant is said, as a matter of fact, to aid against illnesses of the brain, such as depression and melancholy. It also helps the hearth and I find the connection between these two organs very telling (just like the above-mentioned Earth and Sky).
