My deep appreciation to the many, mostly anonymous visionary artists of diverse traditions whose work inspires and informs these books. They were fashioned within a new tradition now being shaped which is linked to our own High Middle Ages. At that time, it is said, artists were not so much creative personalities trying to express themselves, but conspirators in the process of discovering and refining a visual language that could convey a living sense of the sacred. If an artist in Flanders got an Adam and Eve just right, illuminators in Milan and Paris would quickly adopt it into their canon. If an image was true, it belonged to the Great Mystery, and it would be foolish not to utilize it to honor the Great Mystery. These works are presented in similar spirit to all those engaged, once again, in finding a fresh vision of the sacred.
