In an archaic Roman prayer, Maia appears as an attribute of Vulcan, in an invocational list of male deities paired with female abstractions representing some aspect of their functionality. She was explicitly identified with Earth ("Terra", the Roman counterpart of Gaia) and the Good Goddess ("Bona Dea") in at least one tradition. Her identity became theologically intertwined also with the goddesses Fauna, Ops, Juno, Carna, and the Magna Mater ("Great Goddess", referring to the Roman form of Cybele but also a cult title for Maia), as discussed at some length by the late antiquarian writer Macrobius. This treatment was probably influenced by the 1st-century BC scholar Varro, who tended to resolve a great number of goddesses into one original "Terra". The association with Juno, whose Etruscan counterpart was Uni, is suggested again by the inscription "Uni Mae" on the Piacenza Liver.
