The now withdrawn CPDL edition of Missa Ferialis by the Portuguese Francisco Martins has, with Sanctus XVIII, a 4-fold Kyrie g f e ef e d e (incipit & harmonization) c c c cd ed c h (harmonized)/ f f e ef e d e (plainsong, first note evidently a typo). Anyone recognize this?
The Agnus I took for XVIII in French violin clef, but the harmonized part looks like XVIII with g-sharp a for the cadence.
The UCB librarian kindly fetched Portugaliae Musica 50 out of storage for me, answering my second query and allowing me to put a new edition up at CPDL. I also found much Holy Week music, including a one-of-a-kind Luke Passion in which Christ's words alone are set to polyphony, ATB.
