Eusebius (126) , eunuch, and grand chamberlain under Constantius II. Socrates (ii. 2, 16) relates that, after the death of Constantine in 337, Eusebius of Nicomedia and Theognis of Nicaea, bestirring themselves on behalf of the Arians, made use of a certain presbyter in high favour with Constantius, who had before been instrumental in recalling Arius from exile. He persuaded Eusebius the head chamberlain to adopt Arian opinions, and the rest of the chamberlains followed, and prevailed on the empress also. In 359 Eusebius was the mainspring of the plan of Eudoxius and others for dividing the council to be held on the subject of Arianism, making the Western bishops sit at Rimini, the Eastern at Seleucia; part of those in the secret were to sit at each council, and try to gain over their opponents to Arian views. Laymen of influence favoured the plan in order to please the chamberlain (Soz. H. E. iv. 16). On the death of Constantius in 361 Eusebius tried to curry favour with Julian by assuring him of the loyalty of the East (Amm. xxi. 15, Â§ 4); but was unable to avert what Ammianus and Philostorgius represent as the just reward of his deeds. One of the first acts of Julian was to condemn him to death ( ib. xxii. 3, Â§ 12). Ammianus describes him as the prime mover of all the court intrigues of his day, and sarcastically calls the emperor one of his favourites ( ib. xviii. 4, Â§ 33).
