Fatua

Or Fauna Fatua, a Roman goddess identified with Gaea. Known as the kind goddess because of her benevolence towards all creatures. Her offspring were the Fatui, deities of the fields, sometimes good, sometimes evil, later known as Fays, who had to do with enchantment and charms and knew the power and virtue of words, of stones, and of herbs, by which they were kept in youth and in great beauty and in great riches. Morgan le Fay (Fata Morgana) is associated with ancient legend.

It is more probable that Maia was an ancient name of the bona dea, who was also designated by the names of Ops, Fauna, and Fatua.
