The so-called Gelasian Sacramentary (Latin: Sacramentarium Gelasianum) is a book of Christian liturgy, containing the priest's part in celebrating the Eucharist. It is the second oldest western liturgical book that has survived: only the Verona Sacramentary is older. The "Gelasian Sacramentary" comprises the pre-Gregorian three parts, corresponding to the liturgical year, made up of masses for Sundays and feasts, prayers, rites and blessings of the Easter font and of the oil, prayers at dedication of churches, and for the reception of nuns.
