St Isidore of Pelusium

(1), Jan. 2, a reputed bishop of | Antioch (Usuard., Adon.), of which see, however, Baronius (in Mart.) declares that there never was a bishop of that name, nor does Le Quien (Or. Chr. ii. 699 sqq.) mention any. In Mart. Hieron. he is called Isiridonus bishop of Antioch, The tradition is that he was slain by the Arians. If they really killed a bishop of Antioch, it is most likely we should have heard more about it. (Acta SS. Boll. Jan. i. 83.) [G. T. S.J

(2), bishop of Cyrus, ordained to the episcopate by Eusebius of Samosata when the latter was returning from exile in 378 (Theodoret, H. Z. v. 4). Theodoret, who praises Isidore for his eminent zeal, mentions him in a company of bishops who visited Marcian the solitary after Easter in some year not stated (Hist. Relig. cap. 3, p. 1143, in Pat. Gr. Ixxxii. 1331). In 381 Isidore was present at the council of Constantinople, in the records of which his description is corruptly given as Suriensis instead of Cyrensis. (Mansi, iii. 569; Le Quien, Or. Chr. ii, 931.) [C. H.]

(8), one of the Egyptian bishops and confessors, exiled to Diocaesarea in the reign of Valens. He and his fellow exile Adelphius jointly addressed Apollinaris as one in harmony with themselves shortly before Apollinaris broached his heretical opinions, and their letter was subsequently used by Apollinaris for his own purposes against Paulinus of Antioch. (Facundus Hermianens. Def. Trium Capit. lib. iv. cap. 2 in Pat. Lat. xvii. 618 v.) [C. H.Jj
