Architectural Ornament: Banishment and Return

I just checked this book out through interlibrary Loan, I just read the introduction, but it looks like a great book, here's from the back:
"Not until our time has ornament become a subject of debate. In this provocative book, Brent C. Brolin explores why ornament virtually disappeared in the early 20th century. Architectural Ornament: Banishment and Return details the fascinating interplay of art society, politics, and commerce that led to the invention of "fine" art, the elevation of artist above the artisan, and the establishment of originality as the defining characteristic of art."
