Forum Trajani
Eth. Forum Trajani a town in the interior of Sardinia, known only from the Itineraries, which place it on the road from Tibula, through the interior of the island, to Othoca. (itin. Ant. p. 82.) Its site is fixed at a place called Fordongianus, on the left bank of the river Tirsi (Thyrsus), about 16 miles from Oristano, where there are considerable Roman remains, including those of a bridge, and of Thermae on a scale of great magnificence. These doubtless owe their origin to the emperor Trajan. (Valéry, Voy. en Sardaigne, vol. 2.100.35).
