Abstract
Along 19th and 20th centuries, art became a sort of new religion, sometimes coexisting peacefully with the institutional one, sometimes trying to provide what the institutional religion was not able to provide any more. Nowadays, art has adopted many of the solutions, topics and theories that theology has handled since it was born. Arthur C. Danto treats art as a reality whose history is over (and so, a escathological reality) and also as a metaxological (metaxy=between) reality dwelling between two realms. Thus, we cannot decide by pure perceptive means whether something is art or not. This consideration has important consequences for art theory.
