The web book has been updated with a rewriting of the point 7.1. Codicological and paleographical features. This point is an attempt to take stock of the date issue concerning Marciana Gr. Z. 11 (379) and other multilingual manuscripts (see our previous blog post).
If you have any comment or new inputs of this question, do not hesitate to use this blog post. As you know (if not, have a look to our Forword and Part I. Introduction), the web book is a work in progress and we will be happy to improve the content with your feedback.
