The Land of the Anka Bird - A journey through the Turkic heartlands

From the oasis cities of Central Asia to the frozen wastes of eastern Siberia, the photographs of Ergun Çagatay reflect the immensity and drama of the Turkic-speaking world and the vivid lives, beliefs and spirit of its peoples. Caroline Eden pays tribute to a pioneering photographer who travelled more than 100,000 miles to capture these images.
