Dozens of experts such as Matthew Digby Wyatt and Owen Jones were hired to create a series of courts that provided a narrative of the history of fine art. Amongst these were Augustus Pugin's Mediaeval Court from the Great Exhibition, as well as courts illustrating Egyptian, Alhambra, Roman, Renaissance, Pompeian, and Grecian art and many others. During the year of re-opening, 18 handbooks were published in the Crystal Palace Library by Bradbury & Evans as guides to the new installations. Many of these were written by the specialists involved in creating and curating the new displays. So the 1854 guide to the Egyptian Court, destroyed in the 1866 fire, was entitled: 'The Egyptian Court in the Crystal Palace. Described by Owen Jones, architect, and Joseph Bonomi, sculptor'. That which included a description of the dinosaurs was entitled: 'Geology and Inhabitants of the Ancient World. Described by Richard Owen, FRS. The animals constructed by B.W.Hawkins, FGS'. In the central transept was the 4,000-piece Grand Orchestra built around the 4,500-pipe Great Organ. There was a concert room with over 4,000 seats that hosted successful Handel Festivals for many years. The performance spaces hosted concerts, exhibits, and public entertainment. Many famous people visited the Palace especially during its early years, including the likes of Emma Darwin, the wife of Charles Darwin who noted in her diary on 10 June 1854, "Opening Crystal Pal".
