The manuscript Stralsund MS 229, which dates from 1585, is a collection of sacred motets held in the Stadtarchiv of Stralsund, a German Hanseatic town on the Baltic. There were probably six part-books originally, but only four have survived. The manuscript contains 105 works, composed mainly for five or six voices. It spans several generations of composers, from the late fifteenth to the end of the sixteenth century; it therefore includes works composed before and after the Reformation. The variety of styles is impressive, ranging from early Franco-Flemish polyphony to Italian madrigals and works from central Germany.
