Some Greek cities in southern Italy, like Epizephyrian Locri, observed annual spring rites to honor their mythical founders. Citizen families processed to local shrines, sacrificed animals, and recited the city's origin myth — a blend of Greek and native Italic tradition.
Why the equinox?
Festivals linked to city founders often clustered around the vernal equinox, a time of new beginnings. Ancient writers like Diodorus Siculus describe spring as sacred for colonial memory, when the city’s first settlers landed and established the city’s laws and gods.
Ancient sources suggest Epizephyrian Locri held its founder’s festival around the spring equinox, blending Greek hero cult with Italic ritual.
