During construction work in 1963, this commentary by Paschasius
Radbertus on the Lamentations of Jeremiah was discovered along with
9 other manuscripts in a false floor over the Engelberg library. On
the basis of the verse inscription on 1r, the manuscript can be
attributed to the library of Abbot Frowin of Engelberg (1143-1178).
The hand and the decoration correspond to those characteristic of
the Frowin volumes: the text is in black-brown ink with occasional
capitals that are accentuated in red, the incipits and explicits
are rubricated, simple initials are in red ink, and decorative
initials have tendril and bulb motifs in colorful inks (2r, 40v,
73v, 126r, 163r).
