its first thirty years, the Crystal Palace at Sydenham welcomed approximately 2 million visitors a year. The Crystal Palace was destroyed by a fire in 1936, and was never rebuilt. The Grammar of Ornament Through his work at the Great Exhibition, Jones developed a close working relationship with the civil servant Henry Cole (1808–1882) who went on to become the first director of the South Kensington Museum (later to become the V&A). Through his contact with Cole, Jones was able to present his theories on decoration, ornament and polychromy via a series of lectures at the Society of Arts and at the Government School of Design (latter the "Museum of Manufactures"), whose headmaster was the artist Richard Burchett, and which was administered by the newly formed Department of Practical Art at Marlborough House. Jones also advised on the formation of the teaching collections at Marlborough House (much of it acquired from exhibits at the Great Exhibition) which were collated together as the "Museum of Ornamental Art", and which later became the foundation collections for the South Kensington Museum. Both Jones and Cole were concerned that these collections would encourage students to simply copy examples of ornament, rather than be inspired to examine the underlying decorative principles behind the objects. Furthermore, the location of the collections in London made it difficult for students at the provincial Schools of Design to gain access to them. These two factors would undoubtedly have been significant catalysts in motivating Jones to publish, in 1856, what is possibly his longest-lasting legacy: his seminal design sourcebook, The Grammar of Ornament. Through his articles and lectures, Jones had been formulating what he considered to be key principles for the decorative arts, and indeed these principles provided the new educational framework for the Government School of Design at Marlborough House. Jones expanded his propositions to create 37 "general principles in the arrangement of form and colour in architecture and the decorative arts" which became the preface to the 20 chapters of The Grammar of Ornament. The first 19 chapters of the Grammar present key examples of ornament from a number of sources which were diverse both historically and geographically – examining the Middle East in the chapters on Arabian, Turkish, Moresque (Alhambra) and Persian ornament. The final chapter, titled 'Leaves and Flowers from Nature' acknowledges the underlying principle that dictates the design of ornament around the world, which is
