Coherence of visual and epistemic elements in multimodal artifacts for the cultural heritage education : the case study of the Vitruvian man by Leonardo da Vinci

In this article we hypothesize that, in an interactive system for the representation of the knowledge related to a work of art, it is possible to detect a relation between visual coherence (in particular, the coherence of the number of constituent traits in graphical elements) and epistemic coherence (in particular, the coherence of the forms of knowledge), and that this relation affects the readability and the understanding of specific contents of the work of art. This article describes an experimental design which is conceived for verifying the validity of the research hypothesis. The planned research allows to describe a valid criterion for the development of a system of signs and contents related to a work of art.
