A Greek goddess, originally of fortune and chance, and then of prosperity. She was a very popular goddess and several Greek cities choose her as their protectress. In later times, cities had their own special Tyche. She is regarded as a daughter of Zeus (Pindar) or as a daughter of Oceanus and Tethys (Hesiod). She is associated with Nemesis and with Agathos Daimon ("good spirit"). Tyche was portrayed with a cornucopia, a rudder of destiny, and a wheel of fortune. The Romans identified her with their Fortuna.
