Tyche was Fortune — the goddess of luck, of chance, of the unpredictable element in human affairs. In Hesiod she is one of the Oceanids (a relatively minor figure), but her importance grew enormously in the Hellenistic period (after the late fourth century BCE), when the disorientations of the post-Alexander world — the rapid rise and fall of cities and kingdoms, the displacement of populations, the substitution of personal achievement for ancestral standing — gave the principle of luck a new theological prominence. Each of the great Hellenistic cities had its own Tyche, depicted with a mural crown and a cornucopia, embodying the particular fortunes of that city. The famous Tyche of Antioch, sculpted by Eutychides of Sicyon about 300 BCE, was one of the most influential of these images, copied throughout the Hellenistic and Roman world.
The popular reverence for Tyche was great, but the philosophical attitude toward her was more complex. The Stoics distinguished between true fate (which was the rational order of the cosmos) and apparent luck (which was simply our ignorance of the chains of causation that produced events); Tyche, in their view, was a name for the latter. The Epicureans had less use for her; the popular religion continued to honor her without much philosophical refinement. She had no proper mythology of her own — she was a personification, not a narrative figure — but her cult and her iconography were extensive. Her Roman counterpart was Fortuna, who in the Roman period developed a more elaborate cult and mythology of her own, treated in Volume IV.
