Melody from AM2000s, T. 3, p. 279, rsigns from source, extension to "suis" (absent in AM and H) from critical melody, see http://omnigreg.at/wiki/doku.php?id=ant:1675

This score has a cl-lsc2 which is contradictory, on -bus (retibus) rendered here on -is (suis) because of the text extension, and transcribed with episemata but a ligature with the next note
