Tyche was the Greek Goddess of Fortune, Chance and the non-predictable.
Goddess Tyche was the personification of Hope, Luck and Wealth. She was a labile, yet virtuous spirit, mediating between gods and mortals and leading human lives. She was therefore extraordinarily worshipped by the ancient Greeks.
The main symbol of goddess Tyche was a huge horn, inside of which she was keeping all wealth and richness; the horn once belonged to Amalthea, the goat who fostered Greek god Zeus during his infacy. Tyche was carrying the horn with her constantly, occasionaly turning it upside down to spread all its goods to anyone who would meet her on his way.
The Roman name of Tyche is "Fortuna"
