"I use the term ['invisible masterpiece'] as a metaphor for the idea of a work that comprises art in the absolute - a state beyond the reach of every tangible art-work.  ['Invisible masterpiece'], therefore, does not refer to any specific work, but only to an unattainable ideal, a work in which a dream of art (or art as a dream) is incorporated.” —Thank you, Hans Belting, for The Invisible Masterpiece, 2001, p.11.  Thank you, Chris & Anna Celenza, for access to the library from which this book was borrowed.
