Also known as a Gospel Lectionary or pericope book, an evangelary contains the Gospel readings for the Mass, arranged according to the liturgical year. Since an evangelary gives the full reading (pericope) for each feast, and the pericopes are in liturgical order, it is a more practical volume to use in the celebration of mass than a Gospel Book with added capitularies. The evangelary became increasingly popular from the Carolingian period on.
