In Greek mythology, Tyche was the goddess of destiny and controlled the good and bad of fortune and prosperity of a city. Her name means "luck" in Greek. She is often represented wearing a mural crown (a crown like the walls of a city) and often carrying a large horn with all her wealth and richness in it that she sometimes spreads to others. She is a daughter of Oceanus and Tethys, according to Greek poet Hesiod.
Tyche is one of the Oceanids. Oceanids are the daughters of the Titans, Tethys and Okeanos. The story of the Oceanids is told in the Theogony of Hesiod.
