Sources: PragP 47, fols. 105v-114r; TrentC 89, fols. 354v-356r (c.1460-63). Edition used here: Robert J. Snow, The Manuscript Strahov D.G.IV.47 (Ph.D. diss., University of Illinois, 1968), 330-84. The Mass tenor carries the incipit philipi in PragP 47. The motet is underlaid with the texts Salve regina and (in a later hand) Gaude rosa in TrentC89, and O gloriosa mater in PragP 47, and its tenor carries the incipit hilf und gib rat in both sources. Serves as basis for anonymous parody Missa "Philippi" (http://elvis.music.mcgill.ca/node/571).
