E-GU 3 (290v-292r)
David Crawford, p. 172, annotated: "Rubricated "Motete" in the table of contents. The text is a Benedictus antiphon for Wednesday of Holly Week (AM 408)." and "292'293 no music."
In Crawford's catalogue this work appears with the same foliation than the next one (Order number 18, Lamentatione, ff.293v-301r). As Crawford mentions that ff.292v-293r are blank pages between these two works, we are inclined to think that this work (Order number 17, Ante diem) actualy occupies ff.290v-292r.
