or Agrium, in Ancient Geography, a town of Sicily in the Val di Demona, near the river Semetus. The people were called Populus Agryniensis by Cicero; Agrynius by Pliny. It was the birth-place of Diodorus Siculus, as he himself testifies; but he calls it Argyrion, as it is now called S. Philippo d'Argyron, which modern name seems to confirm that Argyrium is the true reading.
