The Essay

The writer Esther Woolfson contrasts the solidity of Aberdeen, the 'Granite City', with the decline of the North Sea oil and gas industry, on which its economy has so relied since the 1970s. It's part of this week's series of Cornerstones - nature writing about rock, place and landscape. Author of 'Field Notes from a Hidden City', about her encounters with Aberdeen's wildlife, Esther reflects on the city's relationship with the North Sea hydrocarbons industry, and how much the city has been affected by the waning oil boom. She contrasts the city's big, public granite Victorian edifices with the slow creation in past millennia beneath the seabed of the oil and gas hydrocarbons which have powered the modern world. Among the other Cornerstones essays this week, the writer Alan Garner reflects upon flint, the stone that has enabled human civilisation, and Sara Maitland considers Lewisian gneiss, so much a rock of ages that it is two-thirds the age of the earth itself.

The writer Sara Maitland conjures with a rock of ages, Lewisian gneiss. Two-thirds the age of the earth itself, and the oldest stone in the UK, it makes up parts of the Northwest Highlands and the Western Isles. It's part of this week's series of Cornerstones - nature writing about rock, place and landscape. Sara reflects on how the gneiss began its slow journey across the face of the earth more or less where Antarctica is today. It is still moving northwards, at about the same speed as our nails grow. 'Gneiss' comes from the German word meaning to sparkle, and Sara wonders whether it's this quality that convinced Neolithic builders to construct the Callanish stone circle on Lewis from this distinctive, ancient stone. The other Cornerstones essays broadcast on Radio 3 this week hears different writers reflecting on how other rocks shape landscapes and us, such as flint, North Sea oil and gas, gypsum, which is the main constituent of plaster, and the clay bricks that define our urban landscapes.

The writer Alan Garner sparks with flint, the stone that, perhaps more than any other, has enabled human civilisation. It's a stone that has featured in some of his novels, such as Red Shift, where the same Neolithic hand axe resurfaces across different times to haunt his characters. And it is time and evolution that he looks at in this essay: "My blood walked out of Africa ninety thousand years ago. We came by flint. Flint makes and kills; gives shelter, food; it clothes us. Flint clears forest. Flint brings fire. With flint we bear the cold." Alan's essay is the first of five Cornerstones this week in which different writers reflect on how a particular rock shapes both people and place.

Its presence says something about our chutzpah in putting a building where it doesn't belong. Producer Clare Walker.

Andrew Hurley on the haunting qualities of Chingle Hall, a 17th-century manor house near Preston. 3/5 Andrew describes the disturbing histories of the inhabitants of the hall and the many paranormal experiences of visitors.

Novelist Melissa Harrison on the joy of 'sleeping with books' at Gladstone's Library in North Wales, the only residential library in the UK.2/5 Melissa explains why the building allows her to sink into a state of uninterrupted concentration, allowing a thread of thought to persist not only over hours but days. Producer Clare Walker.
