The present volume offers a dozen studies of manuscripts of the Tibetan Bon and Naxi Dongba traditions across time and space. While some of the contributions focus on particular features of manuscripts from either tradition, others explicitly bridge the two by considering common codicological and material aspects of selected examples or common themes in the content of the texts. This is the first primarily object-based study to deal with the cultural history and technology of books from the two traditions. It discusses collections of Bon and Naxi manuscripts, the concepts and history of both traditions, the science and technology of book studies as it relates to these collections, the relationship between text and image, writing materials, and the historical and archaeological context of the manuscripts' places of origin. The authors are specialists in different fields including philology, anthropology, art history, codicology and archaeometry. The contributions shed light on trade routes, materials and technologies as well as on reading practices and ritual usage of Bon and Naxi manuscripts.
