This contribution examines a heretofore unknown list of books that survived in a manuscript in the National Library of the Czech Republic with the shelf mark V C 11. The list mentions a total of seven works in ten volumes that note they are "left by the lady" (volumina reposita circa dominam).
This lady is certainly Dorota the soap-boiler, a burgher from the Old Town of Prague. There is a 15th-century handwritten note on the inside cover of the manuscript that states she bequeathed the codex to the Lauda College of the Prague University.
Thanks to the surviving sources, the contribution presents not only the contents of the manuscripts included in the list (which are mostly of a homiletic and exegetic nature), but also the benefactor's social relationships and her property. It was discovered that Jakub the soap-boiler, who Dorota was married to before becoming a widow, was an Old Town burgher who like others enriched himself from the Hussite confiscations.
Besides the family property, Dorota also owned houses left to her by Mikuláš mydlář. In her surviving testament from 1453, Dorota donated her house to the Beguines and bequeathed smaller inheritances to certain leading Utraquist clerics.
Some of the volumes briefly described in the list were found with varying degrees of certainty in the National Library where the collections of the medieval Prague university are stored. Most of them can be proven to have been part of the Lauda College, just like the book in which the list survived.
This fact leads to the hypothesis that the collection probably lists books owned by Mikuláš the soap-boiler, which were then inherited by Dorota. She promised to give the books to the Lauda College; an act that had yet to take place at the time the list was created.
