Nomia was apparently a companion of Callisto, the daughter of Lycaon: Pausanias mentions a painting of the two, with Callisto sitting on a bearskin and her feet lying on Nomia's knees; there is also Pero portrayed next to them. Nomia is also a name for a type of water goddess, many believe that she started off as nothing but a nymph until one day Callisto, decided to trade her love for a god status.
