Chaucer and the Poems of 'Ch'

On several counts, one particular collection of French lyrics made in France in the late fourteenth century, University of Pennsylvania MS 15, is the most likely repository of Chaucer's French poems. It is the largest manuscript anthology extant of fourteenth-century French lyrics in the formes fixes (balade, rondeaux, virelay, lay, and five-stanza chanson) with by far the largest number of works of unknown authorship.
