[없는 문명] 홈이 감긴 원통

Museum catalogue photograph of a grooved cylinder from a civilisation that never existed: a hollow fired-clay cylinder the length of a forearm, its outer surface covered with one continuous extremely fine spiral groove running end to end, wobbling slightly where the maker's hand hesitated. A thin bronze stylus with a bone grip lies beside it. Part of the surface is abraded smooth and the groove is lost there. Purpose unknown — possibly a sound record. Neutral grey seamless background, raking light from the left, a black-and-white scale bar and a small accession card beside the object with no legible writing on it. Archaeological museum catalogue documentation style. No readable text, no letters, no numbers, no logos.
