Numerian (; died November 284) was Roman emperor from 283 to 284 with his older brother Carinus. They were sons of Carus, a general raised to the office of praetorian prefect under Emperor Probus in 282. Early life and Carus' reign Numerian was the younger son of Carus. In 282, the legions of the upper Danube in Raetia and Noricum proclaimed as emperor Numerian's father, the praetorian prefect Marcus Aurelius Carus, after a mutiny against the emperor Probus, in which the latter was killed. By one account, Carus had himself rebelled against the emperor, and Probus' army, stationed in Sirmium (Sremska Mitrovica, Serbia), decided they did not wish to fight Carus and assassinated their emperor instead. According to the Historia Augusta and the view accepted by Gibbon, whose opinion is primarily dependent on the Historia Augusta as a source, Carus was not responsible for Probus's death, and inflicted severe punishment upon the murderers. Carus, already sixty, wished to establish a dynasty and immediately elevated Carinus and Numerian to the rank of Caesar. In 283, Carus left Carinus in charge of the West and moved with Numerian and his praetorian prefect Arrius Aper to the East to wage war against the Sassanid Empire. The Sassanids had been embroiled in a succession dispute since the death of Shapur and were in no position to oppose Carus' advance. According to Zonaras, Eutropius, and Festus, Carus won a major victory against the Persians, taking Seleucia and the Sassanid capital of Ctesiphon (near modern Al-Mada'in, Iraq), cities on opposite banks of the Tigris. In celebration, Numerian, Carus, and Carinus all took the title Persici maximi. Carus died in July or early August of 283, allegedly due to a strike of lightning. Numerian and Carinus as Augusti The death of Carus left Numerian and Carinus as the new Augusti. Carinus quickly made his way to Rome from Gaul, arriving in January 284, while Numerian lingered in the East. The Roman retreat from Persia was orderly and unopposed, for the Persian King, Bahram II, was still struggling to establish his authority. By March 284, Numerian had only reached Emesa (Homs) in Syria; by November, only Asia Minor. In Emesa he was apparently still alive and in good health, as he issued the only extant rescript in his name there. Coins were issued in his name in Cyzicus at some time before the end of 284, but it
