Gnaeus Manlius Vulso was Roman consul in 474 BC with Lucius Furius Medullinus Fusus.
The historian Livy calls him Gaius. Most modern writers refer to him as Aulus, assuming that he is the same person as the decemvir of 451 BC, 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.
Life
His father's name was Gaius (or Gnaeus), and his grandfather's Publius.
In his consulship, Manlius was assigned the war against Veii. The Veientes sued for peace, which the Romans accepted. Upon the Veientes giving tribute of corn and money, a truce of forty years was agreed. As a consequence Manlius gained the honour of an ovation on his return to Rome.
In the following year, Manlius and his colleague were accused by the tribune Gnaeus Genucius, because they had not carried into effect the agrarian law of Spurius Cassius Viscellinus. However, the accusation did not progress as a consequence of the assassination of Genucius.
