Who Isaak was
One of the twenty-two bishops Sozomen names in the roll of those killed in Persia under Shapur II. The list gives the name and the office and nothing further — no see, no date, no detail — and no other ancient source recovers him. Not Isaac, catholicos of Seleucia-Ctesiphon, and not Isaac of Dalmatia.
Named once, in the roll of martyred Persian bishops at Sozomen, Ecclesiastical History II.14; no see, no date, and no other ancient source names him.
Also listed in martyrs and bishops beyond the great sees.
