Tyche was the goddess of fortune and prosperity of a city in Greek mythology. She was the daughter of Aphrodite and either Zeus or Hermes, although some sources referred to her as an Oceanid, a daughter of the Titans Oceanus and Tethys. She was often depicted in statues wearing a mural crown, which is a crown having the shapes of city walls. She was linked to Nemesis, goddess of retribution, and Agathos Daimon (the good spirit). Tyche appeared on many coins of the Hellenistic period (after the death of Alexander the Great in 323 BC).
