Similar observations upon the alphabet, and upon words generally, would not have been without utility; but they would have made the work too long. DIOCLETIAN. After several weak or tyrannic reigns, the Roman Empire had a good emperor in Probus, whom the legions massacred, and elected Carus, who was struck dead by lightning while making war against the Persians. His son, Numerianus, was proclaimed by the soldiers. The historians tell us seriously that he lost his sight by weeping for the death of his father, and that he was obliged to be carried along with the army, shut up in a close litter. His father-in-law Aper killed him in his bed, to place himself on the throne; but a druid had predicted in Gaul to Diocletian, one of the generals of the army, that he would become emperor after having killed a boar. A boar, in Latin, is _aper_. Diocletian assembled the army, killed Aper with his own hands in the presence of the soldiers, and thus accomplished the prediction of the druid. The historians who relate this oracle deserve to be fed on the fruit of the tree which the druids revered. It is certain that Diocletian killed the father-in-law of the emperor, which was his first right to the throne. Numerianus had a brother named Carinus, who was also emperor, but being opposed to the elevation of Diocletian, he was killed by one of the tribunes of his army, which formed his second pretension to the purple. These were Diocletian's rights to the throne, and for a long time he had no other. He was originally of Dalmatia, of the little town of Dioclea, of which he took the name. If it be true that his father was a laborer, and that he himself in his youth had been a slave to a senator named Anulinus, the fact forms his finest eulogium. He could have owed his elevation to himself alone; and it is very clear that he had conciliated the esteem of his army, since they forgot his birth to give him the diadem. Lactantius, a Christian authority, but rather partial, pretends that Diocletian was the greatest poltroon of the empire. It is not very likely that the Roman soldiers would have chosen a poltroon to govern them, or that this poltroon would have passed through all the degrees of the army. The zeal of Lactantius against a pagan emperor is very laudable, but not judicious.
