(Ἵππωνα), from epus (ἵππος), that is, equus, was regarded as the protectress of horses. Images of her, either statues or paintings, were frequently seen in niches of stables. She was said to be the daughter of Fulvius Stellus by a mare. (Juv. 8.157; Plut. Parall. Gr. et Rom. p. 312; Hartung, Die Religion der Römer, vol. ii. p. 154.)
