A liturgical book divided into three parts, containing the instructions and prayers for episcopal functions, outside of Holy Mass, for the sacramental ceremonies, consecrations, personal, local, and real blessings, and for acts of jurisdiction. Such ceremonies of bishops developed in the 10-11th century, from the Sacramentaries and Ordines Romani. Such collections were known as the Liber Episcopalis; Liber Pontificalis, or Ordinarium Episcopi. The first Roman Pontifical was published at Rome in 1485.
