From Wikipedia:
The Roman de Fauvel was first published in Paris in 1314, in a climate of political instability. The text is attributed to Gervais du Bus, a member of the royal administration. It will be successful enough to be still copied in the 15th century. Twelve manuscripts have survived, the most famous of which is probably the fr. BN146, written in 1316.
The BN146 is attributed to Chaillou de Pesstain. Its particular value resides in the additional 3000 verses and 168 musical pieces from the sacred and profane repertoire. The BN146 has often been said to mark the beginning of the stylistic period Ars Nova.
Literary and music critics have often claimed that the musical interpolations were chosen entirely randomly (Paris, 1898; Langfors, 1914; Gagnepain, 1996). However, more recent work has attempted to disprove this hypothesis, showing that the additions contributed by the BN146 are part to a larger artistical project with, beyond the political message, a religious purpose (Herbelot, 1998). Interestingly, the idea that this manuscript was more than an anthology was proposed back in 1935 by Emilie Dankh who gave us then a complete edition of the text of the BN146.
