The chansonnier Paris, Bibliotheque nationale, f. fr. 22543 (known as "R") has been recognized for over 200 years as a precious repository of the literature of the medieval troubadours of southern France. It transmits almost 950 lyric poems and 160 melodies, along with many other important writings in the Occitan language, many of which are unica.
The paleography, decoration, and dialect of the manuscript are described thoroughly, and their distinctive features are seen to support the hypothesis that R was compiled in northern Languedoc or western Provence around 1300. While most of the texts of R were copied by one scribe, the relatively few melodies it contains were probably notated by at least four different copyists. Over eighty percent of the poems were never supplied with their melodies, even though musical staves were provided; these staves were left empty. The notation is in the style of the so-called Notre Dame school of Paris, and the rhythms of the notes are not apparent, although a few seem to be in rudimentary mensural notation.
The manuscript contains some works of the troubadours of the early twelfth century, and also a large number of works by late thirteenth-century poets. By examining internal paleographical data and making comparisons with other extant codices, it is possible to offer suggestions on the nature of the exemplars of this heterogeneous collection. The problems of determining how the texts and melodies were transmitted are investigated, including the issues of oral transmission, the lack of extant autographs, the disparity in the origins of the surviving manuscripts, and the variant attributions. The musical transmission is especially problematic, since only three other sources containing music survive. The forty-five concordances that R shares with these other codices are discussed.
A review of the modern history of the manuscript shows that the earliest known owner was the Marquise d'Urfe of the early eighteenth century. The commonly accepted belief that R was in the library of her ancestor the poet Honore d'Urfe in the seventeenth century is found to be unsupported by the available evidence.
