Appian of Alexandria Civil Wars 2.15.101

[101] When Caesar returned to Rome he had four triumphs together: one for his Gallic wars, in which he had added many great nations to the Roman sway and subdued others that had revolted; one for the Pontic war against Pharnaces; one for the war in Africa against the African allies of L. Scipio, in which the historian Juba (the son of King Juba), then an infant, was led a captive. Between the Gallic and the Pontic triumphs he introduced a kind of ¹ Egyptian triumph, in which he led some captives taken in the naval engagement on the Nile. ² Although he took care not to inscribe any Roman names in his triumph (as it would have been unseemly in his eyes and base and inauspicious in those of the Roman people to triumph over fellow-citizens), yet all these misfortunes were represented in the processions and the men also by various images and pictures, all except Pompey, the only one whom he did not venture to exhibit, since the latter was still greatly regretted by all. The people, although restrained by fear, groaned over their domestic ills, especially when they saw the picture of Lucius Scipio, the general-in-chief, wounded in the breast by his own hand, casting himself into the sea, and Petreius committing self-destruction at the banquet, and Cato torn open by himself like a wild beast. They applauded the death of Achillas and Pothinus, and laughed at the flight of Pharnaces.
