This international conference, held at the University of Lausanne (CH), seeks to demonstrate the major impact of the Digital Era on knowledge, by studying the history of cultural technologies. The present evolution of the Ancient manuscript allows one to detect this turning-point, notably with the digital editions of Homer and the New Testament. The notions of authorship and critical edition are questioned : modern history and contemporary analysis have to be enrooted in ancient memory to reflect upon the digital turn. A public evening will conclude the conference on the 25th August. Org. Claire Clivaz (IRSB, Lausanne).
