Curtains in silk and linen are displayed during the exhibition "Art of the Islamic Civilisation. The al-Sabah Collection" at the Scuderie del Quirinale museum in Rome on July 24, 2015. Kuwait's Sheikh Nasser Sabah al-Ahmad al-Sabah and his wife, Sheikha Hussah Sabah al-Salim al-Sabah have been collecting works of Islamic art and of the art of the Middle East before Islam for forty years, and their collection, comprising some 35,000 items, is unquestionably one of the most important in the world not only in terms of its size but also in terms of the quality and originality of the works of art it contains. The exhibition will open July 25 to September 20, 2015. AFP PHOTO / GABRIEL BOUYS (Photo credit should read GABRIEL BOUYS/AFP/Getty Images)
