Ornaments are omnipresent - they can be found on buildings, fabrics, jewelry, tiles, ceramics and wallpaper. Scorned at the beginning of the modern age, ornament has long since returned to art and architecture and influences design drafts as much as tattoo motifs. In New Grammar of Ornament, Thomas Weil compares current ornamental objects with the results of archaeological research on ornamental artifacts and concludes that there is an anthropological constant. From the recurring arrangements of stripes, rectangles, triangles and dots and the frequency of the forms of floral ornaments used, he derives a new grammar of ornament. More than 160 years after Owen Jones's publication Grammar of Ornament, by publishing his New Grammar of Ornament Thomas Weil is offering a new reference work. It categorizes the variety of ornamental forms used worldwide and for the first time places them in a major art and cultural historical context.
