ALSIUM, in Ancient Geography, a city of ancient Etruria, occupying (according to Cluverius) the spot on which Pala now stands. We are told by Dionysius Halicarnassensis, that Alsium was built by the Aborigines, long before the Tyrrhenians invaded Italy. In this case it must have been founded not long after the dispersion in the days of Peleg. Its founder is said to have been one Alæus, Alesus, or Alisa; whom some conjecture to have been Alisah, or Elisha, the son of Javan, mentioned in Scripture.
