The Dialogue of Timothy and Aquila and Epiphanius of Salamis

Although the Dialogue of Timothy and Aquila is set in Alexandria under the Patriarchate of Cyril (first half of the 5th century), scholars have attempted to identify an earlier version of the text, dating it to the 3d century. This alleged earlier version, however, is not extant as such, and the present article will show that the author of the Dialogue made an extensive use of Epiphanius of Salamis’ De mensuris (dated to 392). The hypothesis that both Epiphanius and the author of the Dialogue used a common source is refuted by a close comparison of the two works in their earliest reconstructable form, taking into account the Georgian-Armenian version of De mensuris and a newly discovered manuscript of the Dialogue .
