The historian Livy calls him Gaius. Most modern writers refer to him as Aulus, assuming him to be the same as the decemvir of 451, who is called Aulus in the Capitoline Fasti.
However, the chronology of this family makes this extremely improbable, leading to the conclusion that he was in fact Gnaeus, the father of the decemvir. The praenomina Gnaeus and Gaius were often confused in early records, which would account for the appearance of that name in Livy"s history.
