Here are my transcriptions of two polyphonic settings surviving in D-As 2 Cod. Aug. 367. Richard Charteris has already pointed out their existence in the 1990s and attributed them to one of the authors of a letter bound in this manuscript, the teacher Hieronymus Walcher. A 19th-century handwritten note, however, suggests that the music may have been composed by a certain Caspar Brinner, who worked as a schoolmaster at St Anna’s from 1565.
