The surviving lists of the attendees and signatories of the First Council of Nicaea are in various languages and from different periods, containing various numbers of the bishops that attended the council. The Latin versions of fragments and complete lists are dated to 6–12th centuries, the Greek version to the 13th century, the Coptic version to the 11th century, the Syriac version dated to the beginning of 6th century and the Arabic version dated to 1398 but is much older. The Armenian versions are dated to the 16–17th centuries but originate from a single archetypal codex written at the beginning of the 11th century.
The list was organized from various sources and published in 1939 as The Original List of the Nicene Fathers by the historian of the Byzantine Empire Ernest Honigmann and has become the standard reference. It was translated into English in 2021.
Bishops from the dioceses of Hispania, Italiciana, East, Pontus, Asia, Thrace and Moesia attended the council.
Historically important attendees included Hosius of Cordoba (1), Alexander of Alexandria (4), Eusebius of Caesarea Maritima (26),Eustathius of Antioch (49), Jacob of Nisibis (77), Leontius of Caesarea Mazaca (91), Aristaces (102). Most of the bishops attending the Council of Nicaea were Greeks.
Athanasius of Alexandria is not on the list but he was an assistant and secretary to Alexander of Alexandria at the council and later his successor. The extant lists of the attendees and signatories of the council were formulated at Athanasius' instigation in 362.
