University of Barcelona - MS 1841

I'm not 100% sure I have all of the metadata accurately transcribed, because the University of Barcelona's website seems to be principly in Catalan, but MS 1841 seems to be a Spanish in origin (maybe around Toledo) Book of Hours from roughly 1480-1520, use undetermined.  The manuscript is nicely executed, with outer-edge borders on most pages and full borders and large historiated initials to start most sections.  The calendar, however, is a mess.  I've not yet written the "visualizing errors" code, but this is the most error-filled calendar I've seen yet.  Out of 218 identifiable saints, 44 seem to have incorrect dates, that is roughly 20%.  Of these, several are major feasts, such as the Apostle Barnabas or Mark the Evangelist.  There's even an extremely rare example of a saint in the wrong date, King Sigismund (May 1) is listed on April 30 (see f.4v below)
