Secret History

The astonishing story of Dr Irving Finkel, a world expert on ancient Babylon, and his incredible discovery of a 4000-year-old tablet that sheds new light on the iconic and world famous biblical tale of Noah's Ark. Having spent 20 years translating the tablet, Dr Finkel sets out to show that the biblical narrative originated from stories that had been embedded in Sumerian and Babylonian society and literature for thousands of years. He also casts new light on the shape of the ark, believing that it was round. The ancient clay tablet, discovered on a mantelpiece in a UK suburban home, is inscribed with the world's oldest language. It tells of the story of Noah and the great flood and gives precise and detailed instructions on how to build an ark. Inspired by his find, Dr Finkel and a team of archaeological boat builders set out to build a real Noah's ark and discover if the ancient immense coracle-shaped boat can float. This iconic and universal story in human history is one of the most epic stories in three of the world's greatest religions: Judaism, Christianity and Islam. This tablet and Dr Finkel's dedicated research and discoveries provide a fascinating new perspective on this pivotal religious story.
