There are few things more in common across cultures than the belief in ghosts. Ghosts inhabit something of the very essence of what it is to be human. Whether we personally 'believe' or not, we are all aware of ghosts and the rich mythologies and rituals surrounding them. They have inspired, fascinated and frightened us for centuries - yet most of us are only familiar with the vengeful apparitions of Shakespeare, or the ghastly spectres haunting the pages of 19th-century Gothic literature. But their origins are much, much older.

Since the Victorian period, it has been understood that the story of Noah, iconic in the Book of Genesis, and a central motif in Judaism, Christianity and Islam, derives from a much older story that existed centuries before in ancient Babylon. But the relationship between the Babylonian and biblical traditions was shrouded in mystery. Then, in 2009, Irving Finkel, a curator at the British Museum and a world authority on ancient Mesopotamia, found himself playing detective.
