 The crusade never took place.There are contemporary accounts of the banquet (notably the "Memoirs" of Olivier de la Marche, and the "Chroniques" of Mathieu d'Escouchy), which name and describe in much detail the lavish entertainments staged during the meal and even the various pieces of music performed, perhaps including Dufay's motet "Lamentatio sanctae matris ecclesiae Constantinopolitanae".At one point in the entertainment, according to the chronicles, an actor dressed as a woman in white satin clothes, personifying the
Church of Constantinople (according to one hypothesis, played by Olivier de la Marche himself) entered the hall of the banquet riding on an elephant, led by a giant Saracen, to recite a "complaint and lamentation in a piteous and feminine voice" (""commença sa complainte et lamentacion à voix piteuse et femmenine""), requesting aid from the Knights of the Golden Fleece.
