 After the formation of the Western Orthodox Church in 1936, the priest Eugraph Kovalevsky, later Saint John of Saint-Denis, set about restoring the Gallican rite for use by the French Church.The principal documents he used that had been unavailable to his predecessors in restoring the Gallican Mass were two letters ascribed to Saint Germanus of Paris (496-576) that describe the liturgy in sixth-century Paris.Kovalevsky drew on the writings of numerous Gallican saints of the same era that provide information on Gallican liturgical practice, as well as extant missals, sacramentaries, lectionaries, and antiphonaries of related rites.
