Quintus Aemilius Barbula (fl. 317–311 BC) was consul in 317 BC, in which year a treaty was made with the Apulian Teates, Nerulum was taken by Barbula, and Apulia entirely subdued. (Liv. ix. 20, 21 ; Diod. xix. 17.) Barbula was consul again in 311, and had the conduct of the war against the Etruscans, with whom he fought an indecisive battle according to Livy. (ix. 30—32 ; Diod. xx. 3.) The Fasti, however, assign him a triumph over the Etruscans, but Niebuhr (Rom. Hist. iii. p. 278) thinks this to have been an invention of the family, more especially as the next campaign against the Etruscans was not opened as if the Romans had been previously conquerors.
Quintus was the first consul in the Barbula branch of the ancient patrician gens Aemilia, said to have come to Rome in the reign of Numa Pompilius. His son Lucius and grandson Marcus also became consuls.
