Bettany Hughes Treasures of the World S02E08 - Azerbaijan

Bettany visits Gobustan in Azerbaijan, and uncovers 40,000-year-old rock art which tells the tales of the earliest inhabitants of this desert landscape. She then heads to Shaki, an important stop for merchants travelling on the ancient Silk Road. She meets weavers still making silk in the traditional way and explores the remarkable palace of glass built from the riches of their trade. Venturing into the Caucasus mountains, Bettany discovers why Azerbaijan is known as the Land of Fire.
