Isorhythmic motet. Date seems to be based on a manuscript source which may be/seems to be a copy, so maybe "at latest 1317." Not sure from what I read whether or not the original ms also are anonymous or attribute it to Vitry, but the former is a possibility.
May not have been published until 1956, according to allmusic.com.
