in the short term, helped to restore frontier defense and the practice of agriculture. The army discipline which Aurelian had repaired was cultivated and extended under Probus, who was however more shy in the practice of cruelty. One of his principles was never to allow the soldiers to be idle, and to employ them in time of peace on useful works, such as the planting of vineyards in Gaul, Pannonia and other districts, in order to restart the economy in these devastated lands. In 279–280, Probus was, according to Zosimus, in Raetia, Illyricum and Lycia, where he fought the Vandals. In the same years, Probus' generals defeated the Blemmyes in Egypt. Either then, or during his previous command in Egypt, he ordered the reconstruction of bridges and canals along the Nile, where the production of grain for the Empire was centered. In 280–281, Probus put down three usurpers, Julius Saturninus, Proculus and Bonosus. The extent of these revolts is not clear, but there are clues that they were not just local problems (an inscription with the name of Probus erased has been found as far as Spain). Following this, Probus then put down a revolt by an unnamed rebel in Britain with the assistance of a certain Victorinus, who was later made consul in 282. During the winter of 281, the emperor was in Rome, where he celebrated a triumph. Probus was eager to start his eastern campaign, delayed by the revolts in the west. He left Rome in 282, travelling first towards Sirmium, his birth city. Assassination Different accounts of Probus's death exist. According to Joannes Zonaras, the commander of the Praetorian Guard Marcus Aurelius Carus had been proclaimed, more or less unwillingly, emperor by his troops. Probus sent some troops against the new usurper, but when those troops changed sides and supported Carus, Probus' remaining soldiers assassinated him at Sirmium (September/October 282). According to other sources, however, Probus was killed by disgruntled soldiers, who rebelled against his orders to be employed for civic purposes, like draining marshes. Allegedly, the soldiers were provoked when they overheard him lamenting the necessity of a standing army. Carus was proclaimed emperor after Probus' death and avenged the murder of his predecessor. Legacy According to the favorable treatment of Gibbon (whose account is largely derived from the Augustan History), Probus was the last of the benevolent constitutional emperors of Rome.
