Statue of Tyche, Roman, 2nd Century AD.

From Enc. Britt.: in Greek religion, the goddess of chance, with whom the Roman Fortuna was later identified; a capricious dispenser of good and ill fortune. The Greek poet Hesiod called her the daughter of the Titan Oceanus and his consort Tethys; other writers attributed her fatherhood to Zeus, the supreme god. She was also associated with the more beneficent Agathos Daimon, a good spirit, protective of individuals and families, and with Nemesis, who, as an abstraction, represented punishment of overprosperous man and so was believed to act as a moderating influence. She was often shown winged, wearing a crown, and bearing a sceptre and cornucopia; but she also appeared blindfolded and with various devices signifying uncertainty and risk. Among her monuments was a temple at Argos, where the legendary Palamedes is said to have dedicated to her the first set of dice, which he is supposed to have invented.
