A partial bifolium from a noted breviary from the second half of the 13th century, containing texts and chants for Sexagesima Sunday. Repurposed as a pastedown (now lifted) at the front on the incunabulum X 69, an edition of Astesanus de Ast's Summa de casibus conscientiae from 1473

An additional strip of parchment from the same parent manuscript has been pasted down to helo repair a split in the front wooden board. 

Two closely-related bifolia from the same manuscript and now detached from their host volume are now Frauenfeld, Kantonsbibliothek Thurgau, FRG 210.
