And Sebastianus, who was still unaware of the emperor’s death, he sent to a more distant post, which had been secretly ordered; for although Sebastianus was a quiet and peace-loving man, he stood in high favour with the troops, and hence he was particularly to be feared at that time.
Accordingly, after Merobaudes turned back, the matter of succession was carefully considered and the plan was unfolded that the boy Valentinianus,[*](This Valentinianus is not to be confounded with another boy of the same name, then nine years old and the son of Valens, although the ancient writers often confuse them. This Valentinian, son of the emperor of the same name, met a violent death in 392, according to Hieronymus.) son of the deceased emperor and then four years old, should be summoned and given a share in the rule. He was at the time a hundred miles distant, living with his mother Justina[*](According to Zos. iv. 43, she was formerly the wife of Magnentius. Cerealis was her brother.) at the country house called Murocincta.
