The chief interest of this text is the interlinear glosses and commentaries from the writings of Bede, Jerome, Gregory, and other Church Fathers.

It is therefore probable that it was written in Switzerland. The color and texture of vellum is frequently an aid in allocating a manuscript to a certain district and time. The XIIth century skins are often yellower than those of later dates as the result of the fact that a weaker lime-water solution had been used in the bleaching process.
