I just came across a small chunky squarish hardcover by Pepin van Roojen published in 2008 by Pepin Press in Amsterdam: Decorative Patterns from Italy. The book is beautifully printed on heavy shiny coated paper. The patterns themselves are in nice jarring colors with lots of sharp-edged intensity. "Most are taken from floor mosaics and wall friezes in Gothic and Renaissance churches, restored and digitized for contemporary use."
Source for these samples is the CD-ROM of images included with the book.
