Writings on the Wall: The Discriminating Use of Scripts in Late Medieval Mural Paintings by
Christian Nikolaus Opitz (Universität Wien):
Christian works on inscription in European wall painting, and his paper examined the uses of different scripts and languages which occur in imagery. He convincingly argued that vernacular language (in this case Catalan) was generally used to refer to the painter, donor or date, and that Latin was employed for Biblical text. Majuscule script was used for epigraphic inscriptions commemorating historical events (to add gravitas), whereas miniscule script was frequently employed to depict spoken words (often rendered in speech scrolls).
