The Ars edendi Lectures are organized by the research programme of the same name based at Stockholm University and funded by the Bank of Sweden Tercentenary Foundation. Both the programme and the lectures focus on editorial method and theory as applied to dynamic textual traditions of medieval Latin and Greek works. In the Lecture Series, leading scholars are invited to share their expertise regarding textual criticism or, as we call it, ‘the art of editing’.In this second volume of lectures, Nicole Bériou o2ers an analysis of medieval Latin sermons, treating oral aspects of written texts and analyzing to what extent traces of a performance can be detected in written testimonies. Traces of orality in a written text also concern punctuation; here, Diether Reinsch and Börje Bydén o2er two diverging approaches on how to deal with medieval punctuation in Byzantine manuscripts, one supporting an adherence to the manuscript usage and the other advocating normalisation. Michael W. Herren discusses the particular challenges involved in editing Latin texts from the pre-Carolingian era. Elizabeth Je2reys describes the edition Michael Je2reys and she made of the letters of Iakovos Monachos, which are almost entirely made up of quotations, and their experiments with a special apparatus to account for variants in the cited texts. David d’Avray examines the theoretical underpinnings of Martin West’s proposed method for dealing with contaminated manuscripts, while Caroline Macé, Ilse de Vos and Koen Geuten compare the results of stemmatological and phylogenetic methods as applied to the transmission of a Byzantine anthology, the Florilegium Coislinianum. / Ars edendi
