then to Greece where he met the young French architect (1803–1834), who was assisting Gottfried Semper (1803–1879) with his radical studies of the polychromy of Ancient Greek buildings. Jones and Goury travelled together to Egypt to study the Islamic architecture of Cairo and the ancient sites, and continued on to Constantinople before finally arriving at Granada in southern Spain where they embarked on their studies of the Islamic decoration at the Alhambra. The Alhambra Jones's studies of the Alhambra in Granada were pivotal in the development of his theories on flat pattern, geometry and polychromy. His travelling companion, Jules Goury, had recently been working with Gottfried Semper on his analysis of the polychromy of Ancient Greek buildings, and this was very likely a key factor in Jones embarking on such a scientific and detailed appraisal of the decoration at the Alhambra. Goury died of cholera – at the age of 31 – during their six-month stay at the Alhambra, and Jones returned to London determined to publish the results of their studies. The standard of colour printing at that time was not sophisticated enough to do justice to the intricate decoration of the Alhambra, therefore Jones undertook the printing work himself. Collaborating with chemists and printers, Jones took it upon himself to research the new process of chromolithography. He subsequently issued Plans, Elevations, Sections and Details of the Alhambra, in twelve parts over a period of almost ten years, from 1836 to 1845. It was the world's first ever published work of any significance to employ chromolithography, and was to be a key milestone in the development of Owen Jones's reputation as a design theorist. Book designs and other printing projects Printing Plans, Elevations, Sections and Details of the Alhambra had been a significant financial strain for Jones, but the publication had gained Jones a huge profile due to its pioneering standards of chromolithography. After, and possibly during, the long gestation period for Alhambra, Jones used his printing press to enter the lucrative market for illustrated and illuminated gift books which were becoming increasingly popular with the Victorian middle class. Jones designed both secular and religious books (collaborating most notably with the publishers Day & Son and Longman & Co.) and developed innovative new binding techniques using materials such as embossed leather, papier-mâché and terracotta – all in an attempt to do justice to the luxurious contents, much of which
