There is fascinating evidence that 5,000 years ago, people living in Britain and Ireland had a deep and meaningful relationship with the underworld seen in the carved chalk, animal bones and human skeletons found at Cranborne Chase in Dorset in a large pit, at the base of which had been sunk a 7-metre-deep shaft. Other examples considered in this Essay include Carrowkeel in County Sligo, the passage tombs in the Boyne Valley in eastern Ireland and the Priddy Circles in the Mendip Hills in Somerset. If prehistoric people regarded the earth as a powerful, animate being that needed to be placated and honoured, perhaps there are lessons here for our own attitudes to the world beneath our feet.
