It is scary and sad to think that those stupid idiot Islamists currently rioting in Europe would destroy all these paintings and other treasures of Western civilization without hesitation. The Europeans need to wake up.
Islamic people have many beautiful mosques and art of their own, of which they should be justly proud. I don't think anyone can outdo their decorative designs (which were an alternative to the realism banned by the Moslems). Below: two images first from the Alhambra in Granada, Spain from the 14th century and then two more images of the Blue Mosque, inspired somewhat by the Byzantine Hagia Sophia in Istanbul.
Interestingly, Akbar in India about 1500 promoted not only a great range of religious viewpoints in his court (from Islam to Buddhism to Christian and Jainism), but the work under his court has its own precious realism. I knew nothing of this until a graduate seminar, which I am very grateful to have taken. The most famous Taj Mahal is a mixture of Mughal, Indian and Islamic styles.
