Without Benedictus. For the attribution of this piece to Compère and its possible belonging to a cycle, see WARD 1986, 499, 506, and 508-515. The attribution was proposed by STAEHELIN 1973, 82, based on the probable identification of this Sanctus with the isolated one attributed to “Loyset” in Librone [4] according to BERWIN-HIRSCHFELD 1892, 91. Ludwig Finscher (s.v. "Compère, Loyset", in "MGG Online") strongly questioned the attribution on stylistic grounds. See also http://www.motetcycles.ch/cycle/426. Due to the complex issues of authorship and rewriting and the web of partial and reworked concordances regarding the entire cycle as proposed by WARD 1986, the problem awaits further investigation. In Librone [4] a G is added at the end of each voice, except in the Altus. Consequently the final there is G and not D as in Librone 2.
