Ulixes, Ulysses, Ulyxes

The Roman name for Odysseus, one of the principal Greek heroes in the Trojan war. According to the Homeric account, he was the grandson of Arcesius, and a son of Laertes and Anticleia, the daughter of Autolycus, and brother of Ctimene.

From The History of Rome by Theodor Mommsen

The same phenomenon appears in particular words: the Roman Pollux and the Tuscan Pultuke are independent corruptions of the Greek Polydeukes; the Tuscan Utuze or Uthuze is formed from Odysseus, the Roman Ulixes is an exact reproduction of the form of the name usual in Sicily; in like manner the Tuscan Aivas corresponds to the old Greek form of this name, the Roman Aiax to a secondary form that was probably also Sicilian; the Roman Aperta or Apello and the Samnite Appellun have sprung from the Doric Apellon, the Tuscan Apulu from Apollon. Thus the language and writing of Latium indicate that the direction of Latin commerce was exclusively towards the Cumaeans and Siceliots.
