Controversy arose when Victor, bishop of Rome a generation after Anicetus, attempted to excommunicate Polycrates of Ephesus and all other bishops of Asia for their Quartodecimanism. According to Eusebius, a number of synods were convened to deal with the controversy, which he regarded as all ruling in support of Easter on Sunday. Polycrates ("circa" 190), however, wrote to Victor defending the antiquity of Asian Quartodecimanism. Victor's attempted excommunication was apparently rescinded, and the two sides reconciled upon the intervention of bishop Irenaeus and others, who reminded Victor of the tolerant precedent of Anicetus.
