Tibula
Tibula ( Greek: , Ptol.), was an ancient town of Sardinia, near the northern extremity of the island, which appears to have been the customary landing-place for travelers coming from Corsica; for which reason the Itineraries give no less than four lines of route, taking their departure from Tibula as a starting-point. (Itin. Ant. pp. 78-83.)
