Valentia
VALE´NTIA (Eth. Valentinus: Nuragus), a town in the interior of Sardinia, SE. of Usellis. It seems to have been a considerable place, as the Valentini are one of the few names which Pliny thought it worth while to mention among the Sardinian towns. Ptolemy also notices the Valentini among the tribes or "4 populi" of the island, and there can be little doubt that the Valeria of the same author is only a false reading for Valentia. (Plin. Nat. 3.12. s. 17; Ptol. 3.3. § § 6, 7.) Its remains are still visible at a village called Nuragus, near the town of Isili, about 12 miles from the ruins of Usellis. The adjoining district is still called Parte Valenza. (De la Marmora, Voy. en Sardaigne, vol. ii. p. 407.) - Dictionary of Greek and Roman Geography (1854) William Smith, LLD, Ed.
