This book will give light to the most recent studies on illuminated manuscripts carried out by the research group "Medieval texts and images," coordinated by Prof. Adelaide Miranda and integrated, as an independent research line, in the Institute for Medieval Studies of the Nova University (Lisbon). New approaches and methodologies have been explored by the members of this group in order to carry out innovative and interdisciplinary research which meant that the group has become a leader in research on illuminated manuscripts in Portugal and one of the largest in the Iberian Peninsula.
