Wegman: Edition: Heinrich Isaac, Opera omnia, ed. Edward R. Lerner, 8 vols. to date, Corpus mensurabilis musicae, 65 ([s.l.:] American Institute of Musicology, 1974- ), 7: 114-34. This recording has been transposed down a step, so as to facilitate comparison with the other two Masses on Une mousse de Biscaye.
Dating based on Grove, which says it was probably composed by 1492.
No model in Wegman (seems not to be based on the same monophonic chanson as Josquin's mass: http://elvis.music.mcgill.ca/node/3927)
