The student, through individual case studies on one or more traditions, conducted starting from the direct examination of manuscript and printed witnesses, will acquire advanced philological tools and active skills to face the main ecdotic, exegetical and interpretative problems of the texts of Italian literature. Through the analysis of various types of autograph materials (sketches, zibaldoni, annotated books, etc.), the student will be able to develop further skills aimed at studying the genesis of the texts and will have the opportunity to refine the methodology of approach to the sources.
