The Art of Hajj by Venetia Porter'It is laid down in the Qur'an that at least once in their lives Muslims should undertake the annual spiritual pilgrimage;the Hajj;to the holy city of Mecca. There, within a sanctuary, lies the Kaba;a cube of black granite that is the literal center of a Muslim's world and the compass point towards which daily prayers are made. Features illuminated manuscripts, wall paintings and photographs, calligraphy, textiles, scientific instruments, decorative tiles, maps, ceramics, metalwork, and powerful works by contemporary artists.
