The Rharian Field (Greek: Ράριον Πεδίον, Rárion Pedíon, [r̥á.ri.on pe.dí.on]) was located in Eleusis in Greece and was supposedly where the first plot of grain was grown after Demeter (through Triptolemus) taught humanity agriculture.[1][2][3] It was associated with the Eleusinian Mysteries.
Demeter was often given the epithet Rharias after the field, or after its mythical eponym Rarus.[3][4]
