Gothic art was and continues to be a technology for engaging beholders in certain forms of visual communication. It is user-friendly, compared to earlier and later visual regimes. Medieval cathedrals, like computers, were constructed to contain all the information in the world for those who knew the codes. Medieval people loved to project themselves into their images just as we can enter into our video and computer screens. In this respect Gothic artists, such as the Italian Giotto (c. 1267-1337), were the first to experiment with what we call “virtual reality.”
