ANIO, (Cicero, Horace, Priscian); ANIEN, (Statius); now il Teverone: a river of Italy, which falls into the Tiber, three miles to the north of Rome, not far from Antennae. It rises in a mountain near Treba, (Pliny); and running through the country of the Aequilii, or Aequi, it afterwards separated the Latins from the Sabines; but nearer its mouth, or confluence, it had the Sabines on each side. It forms three beautiful lakes in its course, (Pliny). In the territories of Tibur it falls from a great height, and there forms a very rapid cataract; hence the epithet praeceptor, and hence the steam caused by its fall, (Horace). Anienus is the epithet formed from it, (Virgil, Propertius). Anienus is also the god of the river, (Propertius, Statius).
