Striking stereo daguerreotype depicting the allegorical sculpture “Una and the Lion,” exhibited at the Crystal Palace during the Great Exhibition of 1851. Seated upon the back of a powerful lion, the serene female figure, Una, derived from Spenser’s The Faerie Queene, embodies purity and moral strength. The lion, cloaked with garlands and carved in deep relief, conveys both motion and submission, highlighting the dramatic symbolism central to Victorian artistic ideals. The richly detailed setting captures the cast iron and glass grandeur of the Crystal Palace interior, with botanical elements and other marble works seen in the background. Mounted in its original stereo format with a chemist’s label from Apperley to the verso, likely a London dealer or preparer of early photographic plates. A rare and vivid glimpse into the sculptural displays of mid-19th century world fairs.
