Chael e Severo in PSI Com. 11 2 (PSI inv. 534)

PSI Com. 11 2 (= PSI inv. 534) contains a prayer for two prelates, Chael and Severus: they are identified, respectively, as the patriarch of Alexandria and the bishop of Antinoupolis, who lived in the 8th century. Therefore the papyrus was not written in the 6th cent., as it was previously believed. In the Appendix P.Berol. Inv. 17612 is reexamined leading to a new dating for the find, 10th cent. instead of 6th cent., as it was previously believed. Moreover, there is a new identification of the prelates mentioned in the prayers contained.
