According to the Internet source given below, Pierre Bouteiller was a French composer. He began as a maître de chapelle in Troyes before moving on to Paris as a player of the viol and other musical instruments. He left only thirteen petits motets and the Missa pro defunctis in five partswhich remained in manuscript form and were collected by Sébastien de Brossard. The traditional, sober and sometimes austere polyphonic writing of the masses by François Cosset and Bouteiller contrast nicely with both the plainsong and the enticing, occasionally Italianate inflections found in the petits motets by French musicians of the time.
