Marcus Aurelius Claudius Quintillus was born at Sirmium in Pannonia Inferior. Originating from a low-born family, Quintillus came to prominence with the accession of his brother Claudius Gothicus to the imperial throne in 268. Quintillus was possibly made Procurator of Sardinia during his brother's reign.
Reign of Quintillus
Quintillus was declared emperor either by the Senate or by his brother's soldiers upon the latter's death in 270. Eutropius reports Quintillus to have been elected by soldiers of the Roman army immediately following the death of his brother; the choice was reportedly approved by the Roman Senate. Joannes Zonaras reports him elected by the Senate itself. Records, however, agree that the legions which had followed Claudius in campaigning along the Danube were either unaware or disapproving of Quintillus' elevation. They instead elevated their current leader Aurelian as emperor. The few records of Quintillus' reign are contradictory. They disagree on the length of his reign, variously reported to have lasted as few as 17 days and as many as 177 days. Records also disagree on the cause of his death. Historia Augusta reports him murdered by his own soldiers in reaction to his strict military discipline. Jerome reports him killed, presumably in conflict with Aurelian. John of Antioch and Joannes Zonaras reported Quintillus to have committed suicide by opening his veins and bleeding himself to death; John reports the suicide to have been assisted by a physician. Claudius Salmasius noted that Dexippus recorded the death without stating causes. All records however agree in placing the death at Aquileia. Quintillus was reportedly survived by his two sons. The Historia Augusta reports Claudius and Quintillus having another brother named Crispus and through him a niece, Claudia, who reportedly married Eutropius and was mother to Constantius Chlorus. Some historians however suspect this account to be a genealogicalfabrication to flatter Constantine I.
Legacy
Surviving Roman records considered Quintillus a moderate and capable Emperor. He was seen as a champion of the Senate and thus compared to previous Emperors Galba and Pertinax. All three were highly regarded by Senatorial sources despite their failure to survive a full year of reign.
