Among the papers read at the Fourth International Catholic Scientific Congress, held at Fribourg, Switzerland, in August, 1897, was one by _William J. D. Croke_ on _Architecture, Painting, and Printing at Subiaco_ as represented in the Abbey at Subiaco. The author regards the features of the three arts represented in this place as evidence that the record of the activity of the foundation constitutes a real chapter in the history of progress in general and of culture in particular.
