Emperor Carus in the summer of 283 CE, during one of the military expeditions during a strong storm, was probably struck by lightning.
Roman historian Sextus Aurelius Viktor mentions this in the Epitome de Caesaribus. However, there are different versions of the emperor’s death. According to Scriptores Historiae Augustae the ruler was to die because of illness; and according to Joannes Zonaras (a Byzantine chronicler) he was mortally wounded during the war with the Persians.
Another version says that the ruler was the victim of a plot under the prefect of Lucius Flavius Aper.
