Because Arius in a letter addressed Eusebius of Nicomedia as "sylloukianistes" ("Fellow-Lucianist"), Lucian's theology came to be associated with the Arian controversy. Following Adolf von Harnack, many scholars have interpreted the word (which only appears in this instance) as denoting a theological school and have therefore seen not only Eusebius but also Arius and other Arian leaders (among them Maris, Theognis of Nicaea and Asterius) as pupils of Lucian and have transferred Arian views unto Lucian. The first writer to clearly attest such a discipleship for a number of Arian sympathisers—but not for Arius and his closer associates—was the Anomoean church historian Philostorgius.
