In 427 BC Papirius held the consulship together with
Gaius Servilius Structus Ahala. Nothing is known of the events during their consulship. Five years later, in 422 BC, Papirius would again reach the
imperium, this time as a consular tribune together with
Lucius Manlius Capitolinus and
Quintus Antonius Merenda. There is little recorded of the actions of the consular college, but the year saw a large trial being held against the former consul
Gaius Sempronius Atratinus. Sempronius had the previous year held command against the
Volscians and was being prosecuted for needlessly endangering his legion. The prosecution was led by the
Tribunes of the Plebs, of which
Lucius Hortensius was the main prosecutor. Sempronius had succeeded with getting four of his former officers elected as Tribunes of the Plebs to oppose Hortensius. The tactic only partially worked and simply delayed his conviction, which came in 420 BC in the form of heavy fines. In the same year as the conviction fell for Sempronius, 420 BC, Papirius was appointed as
Interrex to hold the
comitia. In this role he most likely oversaw the change from consuls in the previous year to a return to the use of consular tribunes. Papirius was elected as one of two censors in 418 BC. His colleague in the office is not known. This was the first year of consular office for his son or brother
Marcus Papirius Mugillanus and the second term as consular tribune for his former consular colleague Servilius. The actions of the censors are not recorded as ancient chroniclers instead focused on the events relating to the war with the
Aequi and
Labici. == Conflicting Traditions ==
