Owen Jones, The grammar of ornament, London, Day and Son, 1856, State Library of Victoria.

Owen Jones was an architect and one of the most significant design theorists of the 19th century. He published The grammar of ornament in 1856 to improve the taste of contemporary designers by revealing the universal design principles that lay behind all historical ornament. Edward La Trobe Bateman worked on the book with Jones and its influence can be seen in his decorative schema for Queen’s Hall.
