Istanbul, capital of two great empires, confluence of Asia and Europe, has called forth poetry throughout her long history, from paupers and sultans, natives and visitors alike. When Mehmed the Conqueror first wandered through the ruins of the Byzantine palace, it was with the words of the Persian poet Ferdowsi on his lips: The spider spins his web in the Palace of the Caesars/An owl hoots in the towers of Afrasiyab. Since then the silhouette of thousand-year-old domes and tapering minarets, the sunsets reflected nightly in a thousand palace windows and the bustle of her markets have inspired Sultan Suleyman, W B Yeats and Nazim Hikmet, amongst others, to salute one of the world's most remarkable cities.
