This is the “Sahara Circle” by Richard Long CBE. Created in 1988, the work is a digital print on paper mounted onto aluminium, a record of a walk through the Hoggar region of the Sahara in southern Algeria. Long literally laid out a ring of rocks, carving a circular clearing in a patch of broken stones. He explains that circles belong to all people at all times, a universal, timeless shape that carries emotional power without symbolism. The photograph focuses on the ring, with a dramatic stone finger jutting into the horizon above the flat, barren desert. Long’s practice stems from walking itself as a gesture of mark‑making, transforming the landscape into a temporary sculpture that he then captures and brings into the gallery as a photograph. The piece is a clear example of his exploration of geometry, abstraction, and the relationship between human action and the natural world.
