There appears to be nothing in this letter or in Letter CII. also addressed to bishop Basil to identify the recipient. Basil bishop of Seleucia in Isauria was at the Latrocinium and at Chalcedon. Basil, bishop of Trajanopolis was also present at the same councils. Garnerius is in favour of the former, and notes the date as 448.
