Ceillier (x. 42) repeats the charge of distinct errors in chronology in (a) the statement that Arius died in 325 instead of in 336; (b) the extension of the exile of Athanasius by four months; (c) the election of Ambrose at the beginning of the reign of Valentinian, instead of ten years later; (d) the troubles at Antioch placed after instead of before those at Thessalonica; (e) the siege of Nisibis in 350 confounded with that of 359. As to (a) the truth is that Theodoret is guilty rather of vagueness than of a misstatement. (Vide I. capp. xiii, xiv.) The objection to (b) the two years and four months exile of Athanasius is due to Valerius (obs. Ecc. i). Canon Bright (Dict. Christ. Biog. i. 187) agrees with Theodoret (cf. Newman Hist. Tracts xii and Hefele, Conciliengesch. i. 467.) In (c) Theodoret is vague, in (d) wrong. According to Valerius Volagesus, and not Jacobus, was bishop of Nisibis in 350.
