[1] It may have been written for the wedding of Carlo Malatesta and Vittoria di Lorenzo in Rimini.
[2] Many other composers wrote Missae sine nomine, including Walter Frye, Barbingant, Alexander Agricola, Johannes Tinctoris, Matthaeus Pipelare, Heinrich Isaac, Pierre de La Rue, Josquin des Prez, Jean Mouton, Vincenzo Ruffo, and others.
Some masses sine nomine, i.e. based on freely-composed material, were actually named in other ways: the most famous is Giovanni Pierluigi da Palestrina's Missa Papae Marcelli, the Pope Marcellus Mass, which according to a somewhat exaggerated legend persuaded the Council of Trent not to ban polyphonic writing in liturgical music.
[3][4] A myth dating from the time of the Council of Trent was that a Missa sine nomine hid a secular tune, and the listeners were expected to "get the joke"; however the practice of writing masses on freely-composed material predated the Council of Trent and the Counter-Reformation.
[3] In 1977, Leon Schidlowsky composed a work that he called Misa Sine Nomine and dedicated to the Chilean human rights activist Victor Jara; the text is a juxtaposition of part of the mass ordinary with both Bible verses in Hebrew and contemporary texts, and he wrote it for different combinations of narrator, choirs, organ and percussion.
