Nysaeus

Nysaeus, Ny'sius, Nyseus (Νυσήϊος), or Nysi'gena, a surname of Dionysus, derived from Nysa, a mountain or city, either in Thrace, Arabia, or India, where he was said to have been brought up by nymphs. According to some, it was derived from Nisus, who is said to have been his father, or at least to have educated him. (Hom. Il. 6.133, Hymn. 25.5; Apollon. 2.905, 4.431; Diod. 1.15, 3.68; Cic. de Nat. Deor. 3.23; Verg. A. 6.806; Ov. Met. 4.13.) [L.S]

(Νυσαῖος), son of the elder Dionysius, tyrant of Syracuse, by his wife Aristomache, the daughter of Hipparinus. (Diod. 16.6.) We know nothing of the steps by which he rose to the supreme power at Syracuse; but it seems probable that he succeeded his brother Hipparinus in the sovereignty, which he held until B. C. 346, when he was expelled by his half-brother, the younger Dionysius. (Plut. Tim. 1.) He was chiefly remarkable for his love of drinking and his immoderate addiction to gross sensual indulgences. (Theopomp. apud Alten. x. pp. 435, 436; Aelian, Ael. VH 2.41.) [E.H.B]
