A liturgical book containing the Epistles of the Mass. In the Middle Ages the book was called Apostolus (Ordo Romanus, I, iii,ed. Mabillon) or Lectionarium in contrast to the Evangelium or Gospel Book. In France as early as the 9th century the Epistles and Gospels appeared in one book. The Pontificale Romanum orders that the candidate for the subdiaconate must touch the Liber Epistolarum or Epistolary.
