Leo 36 was bishop of Aspendos in Pamphylia; in 787 he attended the Second Council of Nikaia (the Seventh Ecumenical Council) and was probably present at all eight sessions, from 24 September to 23 November 787: Mansi XII 998-XIII 486. In the lists of those present at the first and seventh sessions he is styled Λέοντος ἐπισκόπου Ἀσπένδων: Mansi XII 998, XIII 369 (Ἀσπένδου). Elsewhere he is styled Λέων ἀνάξιος ἐπίσκοπος Ἀσπένδου or similar: Mansi XIII 145, XIII 392. At the fourth session he subscribed the statements read out from the Fathers in support of the veneration of icons: Mansi XIII 145. At the seventh session he subscribed the statement of the faith adopted by the Council: Mansi XIII 389. His name is missing from the list of those at the second session who supported pope Hadrian I (Hadrianos 1)'s statements about icon veneration, possibly through scribal error (the preceding bishop was called either Leontios or Leo; the similarity of name may have led to a scribe omitting his entry).
