Tyche

In Greek mythology, Tyche (Τύχη,meaning "luck" in Greek, Roman equivalent: Fortuna) was the presiding tutelary deity that governed the fortune and prosperity of a city, its destiny. Increasingly during the Hellenistic period, cities had their own specific iconic version of Tyche, wearing a mural crown (a crown like the walls of the city). In literature, she might be given various genealogies, as a daughter of Hermes and Aphrodite, or considered as one of the Oceanids, daughters of Oceanus and Tethys or Zeus Pindar. She was connected with Nemesis and Agathos Daimon ("good spirit").
