In this account of how Spanish painters of the 16th and 17th centuries dealt with mystic visions in their art, and of how they attempted to "represent the unrepresentable", Victor Stoichita aims to establish a theory of visionary imagery in Western art in general, and one for the Spanish Counter-Reformation in particular. He describes how the spirituality of the Counter-Reformation was characterized by a rediscovery of the role of the imagination in the exercise of faith. This had important consequences for painters such as Velasquez, Zurbaran and El Greco, leading to the development of ingenious solutions for visual depictions of mystical experience. This was to crystallize into an overtly meditative and didactic pictorial language.
