And in Greek Hippius, occurs as a surname of several divinities, such as Neptune (Poseidon), who had created the horse, and in whose honour horse-races were held (Serv. ad Virg. Georg. i. 12; Liv. i. 9.) The Roman goddess Fortuna bore the same surname, and the consul Flaccus vowed a temple to her in B. C. 180, during a battle against the Celtiberians. (Liv. xl. 40, xlii. 3.) Tacitus (Ann. iii. 71) mentions a temple of Fortuna Equestris at Antium.
