This is from the Taschen website regarding their book, The World of Ornament:
"Imagine having an opulent compilation of history's most elegant and beautiful patterns and designs at your fingertips - to use, peruse, admire, and be inspired by. World of Ornament brings together the two greatest encyclopedic collections of ornament from the 19th century chromo-lithographic tradition: Auguste Racinet's L'Ornement polychrome Volumes I and II (1875/1888) and M. Dupont-Auberville's L'Ornement des tissus (1877). Adapted from historical items dating back to antiquity, such as jewelry, tiles, stained glass, illuminated manuscripts, textiles, and ceramics, these ornamental designs encompass a wide range of cultural aesthetics including classic Egyptian, Greek, Roman, and Etruscan motifs, Asian and middle-Eastern patterns, as well as European designs from medieval times through the 19th century."
