Brakujący element”, czyli o nieznanym nadaniu dla klasztoru wallombrozjanów w Coltibuono z 1201 roku

The paper contains a commentary accompanying an edition of the 13th century rotulus, recently discovered in the collections of the Jagiellonian University, from the archive of the monastery of Vallombrosians in Coltibuono. The discovery considerably improves current knowledge about land endowments to that monastery at the turn of the 12th and 13th centuries.
