51. [PROCESSIONAL, for Dominican Use]. Seville: Meinardus Ungut and Stanislaus Polonus, 3 April 1494.

The first edition of the processional music used by the Dominican Order was one of only a dozen fifteenth-century Spanish editions printed with musical notation. Although it was printed more than five centuries ago, the book is not truly rare, as an old crate containing more than one hundred unused copies was discovered in a Spanish monastery in 1912. Bridwell Library’s copy, which shows signs of continuous use over the centuries, did not belong to this group. Printed in red and black inks and rubricated in red and blue, it also bears later musical and textual alterations in brown ink.
