43 a.C. Aulo Irzio Gaio Vibio PansaIrzio e Pansa erano i due consoli in carica l'anno 43 a.C. - Per entrambi la fine avvenne prematuramente.
"As Hirtius lost his life in battle during this war, and Pansa shortly afterwards from a wound, the rumour spread that he had caused the death of both, in order that after Antony had been put to flight and the state bereft of its consuls, he might gain sole control of the victorious armies. The circumstances of Pansa's death in particular were so mysterious, that the physician Glyco was imprisoned on the charge of having applied poison to his wound. Aquilius Niger adds to this that Augustus himself slew the other consul Hirtius amid the confusion of the battle".

Il 15 marzo del 44 a.C. Cesare fu ucciso ed Irzio sostenne Marco Antonio, il quale intendeva vendicarne la morte uccidendo Decimo Giunio Bruto, divenuto nell'aprile dello stesso anno governatore della Gallia Cisalpina, verso la quale Antonio aveva avanzato pretese, finché Cicerone non lo convinse a sposare la causa senatoria. Dovette dunque partire per Modena, dove Antonio si stava dirigendo per combattere Bruto, assieme all'altro console, Gaio Vibio Pansa, e ad Ottaviano. Combattuta la battaglia di Modena, entrambi i consoli morirono: Irzio prima in battaglia il 21 aprile, Pansa per le ferite riportate il 23 aprile.
On the other side it was argued that "filial duty and the critical position of the state had been used merely as a cloak: come to facts, and it was from the lust of dominion that he excited the veterans by his bounties, levied an army while yet a stripling and a subject, subdued the legions of a consul, and affected a leaning to the Pompeian side. Then, following his usurpation by senatorial decree of the symbols and powers of the praetorship, had come the deaths of Hirtius and Pansa, — whether they perished by the enemy's sword, or Pansa by poison, sprinkled on his wound, and Hirtius by the hands of his own soldiery, with the Caesar to plan the treason. At all events, he had possessed himself of both their armies, wrung a consulate from the unwilling senate, and turned against the commonwealth the arms which he had received for the quelling of Antony. The proscription of citizens and the assignments of land had been approved not even by those who executed them.

Insomma, un Ottaviano "peacemaker" col pugnale invece che con la colt.
