Off on a Comet: Workers Sewing Sailcloth in Subterranean Cave

In this scene from Jules Verne's Off on a Comet (Hector Servadac), a group of survivors labors deep within a cavernous grotto on the comet Gallia, stitching together large sheets of fabric, likely for a balloon or sail. A supervising figure in a cap directs the work while others sew and fold the material amid crates of supplies. Stalactites hang from the shadowy ceiling, rendered in dramatic Victorian engraving style typical of Verne's illustrated editions.
