A single bifolio, rubbed on one side although still legible, of which part of the topmost musical staves have been cut off. This is the outermost leaf of a gathering (as suggested by the presence of a catchword on the final folio) of a lost host manuscript of which another motet fragment, S-Sr 813, survives and to which the organum fragment S-Sr 535 possibly also belonged. Double-column format with alternating red and blue pen-flourished initials. Roman numerals at the top of folios (as present in S-Sr 813) have here been cut off, but a small parchment strip that accompanies the fragment, and which one belonged to an additional bifolio (now lost) that made up an original double-bifolio wrapper (as in S-Sr 813), bears traces of the numerals XII and XIII. The notation is Franconian: there are texted pairs of semibreves but no dots of division. The first motet, Non pepercit/Non pepercit/Mors (of which the middle portion survives) is known from D-Bas Lit. 115 and the table of contents in F-B 1, 716. The second, O Maria virgo davitica/O Maria maris stella/Veritatem (of which only the beginning is missing) is one of the most widely-transmitted thirteenth-century motets, which here appears with a more elaborately decorated triplum voice than in any other source. The motet cued by the catchword, legible as ‘Ave virgo re?ia’, is probably Ave virgo regia/Ave gloriosa mater/Domino (which follows O Maria/O Maria/Veritatem also in other sources), but could alternatively be Ave virgo regia/Ave plena gratia/Fiat (a contrafactum of a vernacular motet found in D-Bas Lit. 115).

Writing block of ca. 125 x 90 mm. Ruled red staves of five lines; double column.

No foliation. Individual motets are numbered with Roman numerals, in alternating red and blue ink.

Two French three-voice ‘double’ motets (i.e. with independent upper-voice texts). Both of the motets are incomplete and the incipit of a third motet is cued by a catchword. All of the motets are known from other sources.
