As printing became cheaper, the single ornament print turned into sets, and then finally books. From the 16th to the 19th century, pattern books were published in Europe which gave access to decorative elements, eventually including those recorded from cultures all over the world. Andrea Palladio's "I quattro libri dell'architettura" (Four Books on Architecture) (Venice, 1570), which included both drawings of classical Roman buildings and renderings of Palladio's own designs utilizing those motifs, became the most influential book ever written on architecture. Napoleon had the great pyramids and temples of Egypt documented in the "Description de l'Egypte (1809)". Owen Jones published "The Grammar of Ornament" in 1856 with colored illustrations of decoration from Egypt, Turkey, Sicily and Spain. He took residence in the Alhambra Palace to make drawings and plaster castings of the ornate details of the Islamic ornaments there, including arabesques, calligraphy, and geometric patterns. Interest in classical architecture was also fueled by the tradition of traveling on The Grand Tour, and by translation of early literature about architecture in the work of Vitruvius and Michelangelo.
