Abstract
St. Vitus building accounts from the period between 1372 and 1378 are an important source for the history of medieval architecture and the construction of St.
Vitus Cathedral. Regular records and the relatively neat Gothic cursive script suggest that the accounting manuscripts included documents created during the weekly operation.
Then they were thematically organized and documented in the surviving files by the accountant. The accounting based on documents of a temporary nature also shows some typing errors, especially word duplication and crossing or scraping out errors caused by the oversights of the clerk copying the records.
Despite these shortcomings, the weekly accounts were neatly compiled and they mainly served as a basis for the financial audit. The accounting entries were recorded in loose paper quires that were later bound in two codices with a protective limp parchment binding.
The historical interest in both the manuscripts was reflected in Early Modern explanatory memoranda within the accounting records and titles on the parchment covers. The cover of second manuscript was made from a no longer needed notarial instrument, which was removed from the manuscript during the organization of the chapter archives between 1877 and 1890.
It was returned to the codex thanks to the conservation survey of the manuscripts in the chapter library and archives at the beginning of the 21st century.
