Commemoration and Sources
Nicanor is remembered as a venerable (monastic) saint and wonderworker connected with Mount Calistratus in Greece. The Orthodox Church in America's synaxarion entry for his feast day notes the commemoration without supplying a narrative of his life.
Eastern Orthodox liturgical lists for August 7 place him among the post-schism Orthodox saints and give his repose variously as 1419 or 1549; the surviving record does not resolve the discrepancy, and no birth date, place of origin, or detailed account of his monastic life has been preserved in the reachable sources.
