La "Tresplaisante et recreative hystoire du trespreulx et vaillant chevallier Perceval le Galloys..." (1530), mise en prose tardive du 'cycle' du Graal

The Perceval printed in 1530, which collects under a single title the prose adaptations of fi ve works related to the Conte du Graal of Chrétien de Troyes, is based on a manuscript that has since been lost. Th e aim of this article is to verify, by the means of a survey of the entire text, the possible relationship with any of the existing manuscripts of the verse romances. Although neither of these constitutes " the " source of the prose writer, the 1530 adaptation does shed light on the poems' textual tradition as well as suggest some variants which may stem back to the " originals ".
