 In tracing the history of this liturgy, scholars have been for a long time misdirected by a 16th-century forgery under the name of St. Proclus, Archbishop of Constantinople (434-446).This forgery, as has been demonstrated in 1962 by F. J. Leroy, has to be ascribed to Costantin Palaeocapa and it falsely stated that Saint Basil shortened the length of the liturgy for the slothfulness and degeneracy of men.The Byzantine Liturgy is used in the countries which were evangelized from Constantinople, or which came under its influence for any considerable period.
