Nomos

Metapontion's agricultural wealth — built on the grain surplus of the Tarentine Gulf's interior plains — funded one of the most prolific silver coinage programs in Magna Graecia through the fourth century. The city had been a Achaean foundation, and its coinage maintained unusually consistent fabric and weight standards across generations, even as neighboring mints fluctuated under Syracusan pressure and Lucanian encroachment. By the mid-fourth century, Lucanian raids were already beginning to strangle Metapontion's hinterland, and the mint output that had once seemed inexhaustible was entering its terminal contraction.
