For centuries, blue marl was dug from the earth and applied as a soil conditioner. In the seventeenth century, during a period of intensified colonial exploitation in Ireland, marl was described as “grease of the earth” and marketed extravagantly to English gentlemen farmers.

Through prints, video and sculptural objects, Rowan Lear draws on her fascination with marl to consider broader ideas of extraction and embodiment. Adheres to the tongue associates the birth of modern science, its ordering of the senses and depletion of the earth with the persistence of alchemy, sensation and liveliness in geological and photographic processes.
