This lithograph by Henri Fantin-Latour depicts a dramatic moment from Richard Wagner's opera "Tristan and Isolde," capturing the lovers' secret nighttime meeting as Isolde signals to Tristan from her chamber. Fantin-Latour's composition emphasizes the tension and romance of the scene through his delicate handling of light and shadow, with the figure of Isolde rendered in luminous tones against the darker surrounding space. The work demonstrates the artist's skillful command of the lithographic medium and his interest in translating operatic narratives into visual form.
