L objectif de cette étude est double : faire connaître un texte encore non édité à partir de la transcription la plus fidèle possible d un manuscrit sélectionné comme un témoin historique authentique au plan de l histoire littéraire mais aussi d un état de langue donné. La transcription méthodique du texte sert donc à mettre au jour certaines pratiques linguistiques du copiste. On y observe des usages graphiques qui dépassent la fonction phonogrammique, reconnue comme primordiale à l origine, pour atteindre à un usage morphogrammique mis en valeur par des graphies spécifiques faisant apparaître la récurrence de morphèmes grammaticaux et lexicaux ; d autre part, des micro-systèmes apparaissent à travers l emploi original des séquences et des segmentations graphiques qui, dans ce manuscrit, procèdent bien souvent d un geste réflexif. Ces observations conduisent à penser qu une grammaire du français remonte au-delà du XVe siècle. On décèlerait ainsi chez ce copiste une amorce de réflexion grammaticale sur la procédure de mise en texte de son manuscrit qui annoncerait la mise en théorie du français, caractéristique du XVe et surtout du XVIe siècles. Alors qu il se situe bien antérieurement à toute forme de norme prescriptive, ce manuscrit, qui à côté d usages linguistiques plus traditionnels (XIIe-XIIIe siècles) met en place un certain nombre de micro-systèmes tant dans le fonctionnement des graphies que dans celui des séquences graphiques, n en annonce pas moins quelques uns des principes qui conduiront à la codification standardisée du français. De ce point de vue, il permet de déceler l existence d un continuum dans l histoire des pratiques manuscrites du français, inscrivant cette étude dans les perspectives de la recherche contemporaine sur la Diachronie du français.

Giant meteorite impacts during Earth's early history likely had significant effects on early life. We studied the effects on the surface environment and life of a Paleoarchean impactor ~50 to 200× larger than the famous K-Pg impactor. The ...Large meteorite impacts must have strongly affected the habitability of the early Earth. Rocks of the Archean Eon record at least 16 major impact events, involving bolides larger than 10 km in diameter. These impacts probably had severe, albeit temporary, ...

Structures from the Stone Age can provide unique insights into Late Glacial and Mesolithic cultures around the Baltic Sea. Such structures, however, usually did not survive within the densely populated Central European subcontinent. Here, we ...The Baltic Sea basins, some of which only submerged in the mid-Holocene, preserve Stone Age structures that did not survive on land. Yet, the discovery of these features is challenging and requires cross-disciplinary approaches between archeology and ...
