1. There is no doubt that Du Fay’s motet Nuper Rosarum Flores was written to celebrate the rededication of the cathedral by Pope Eugenius IV, but it is still unclear when it would have been performed, or under what circumstances. See chapter 5 for specific discussion of this motet and its performance. It has been proposed that Du Fay’s motet Lamentatio sanctae matris ecclesiae Constantinopolitanae was performed at the Feast of the Oath of the Pheasant, first brought to modern attention by Johan Huizinga in The Autumn of the Middle Ages (1919). F. Alberto Gallo describes the feast but suggests that Du Fay’s motet was written a year later, in 1455. See Music of the Middle Ages II (Cambridge: Cambridge University Press, 1985), 104.

3. The most up-to-date summary of Du Fay’s career can be found in Alejandro Enrique Planchart, “Du Fay, Guillaume, §1: Life,” Grove Music OnlineOxford music online, 2001, updated 2004. Du Fay was in Cambrai from December 1439 through March 1450. After that he traveled for two years, spent six years in Savoy. He returned to Cambrai for good in 1458, remaining there until his death on November 24, 1474.
