Quintus Sulpicius Camerinus Praetextatus

Sulpicius was elected consul or consular tribune in 434 BC. Livy, basing his account on the writings of Valerius Antias and Aelius Tubero, lists Sulpicius together with Marcus Manlius, as the consuls of 434 BC. This Livy writes next to a secondary and contradictory tradition based on the writings of Licinius Macer, which places Gaius Julius and Proculus Verginius as being re-elected as consuls after having held the consulship the previous year. Diodorus Siculus provides a third narrative which includes both Manlius and Sulpicius together with a third individual, Servius Cornelius Cossus, but as consular tribunes, not consuls. Modern consensus generally favor either of traditions including Manlius and Sulpicius, with the classicist Broughton commenting that the re-election of the consuls of 435 remains the least likely version.[3][4][5]

In either case, the actions of the consuls or consular tribunes of 434 BC is not well documented and they relinquished their imperium in favor of the appointment of a dictator. The dictator, Mamercus Aemilius Mamercinus, fought the Falerii and Etruria and enacted a law limiting the term of the censorship to one and a half year, down from the previous five years.[6][7][8]

Sulpicius was appointed as one of the legates under the dictator Aulus Postumius Tubertus in 431 BC. They successfully fought the Aequi and Volsci and defeated them at Mount Algidus. The dictator, Tubertus, had previously been the magister equitum in 434 BC under Aemilius.[9][10]
