Giotto is considered by many to be the founder of modern painting. This thesis is discussed and modified in the present volume on an empirical basis. What emerges is that Giotto's impact cannot be reduced simply to the introduction of the study of nature. Rather, his art was involved in the development of pictorial idioms that were attuned to the skills and interests of their audiences. The new approaches in his painting contributed in particular to the possibility of examining and communicating psychological, narrative and allegorical content of great complexity outside the media of language and text, which not only changed the face of European art but certainly contributed to the intellectual opening of Western societies.
