Eunomius of Cyzicus

Eunomius /juːˈnoʊmiəs/ (Greek: Εὐνόμιος Κυζίκου) (died c. 393 AD), one of the leaders of the extreme or "anomoean" Arians, who are sometimes accordingly called Eunomians, was born at Dacora in Cappadocia or at Corniaspa in Pontus.

[3] Here his free utterance of extreme Arian views led to popular complaints, including those from a number of contemporary writers such as Andronicianus.

[2] During the reigns of Julian and Jovian, Eunomius resided in Constantinople in close intercourse with Aetius, consolidating a dissenting party and consecrating bishops.

[2] In 383, the emperor Theodosius, who had demanded a declaration of faith from all party leaders, punished Eunomius for continuing to teach his distinctive doctrines, by banishing him to Halmyris in Scythia Minor.

[5] The exposition of faith, called forth by the demand of Theodosius for the "council of heresies" in 383, is still extant, and was edited by Valesius in his notes to Socrates of Constantinople, and by Ch.
