These wall art  illusionistic depictions of allegorical sculptures from the Palazzo Valle Marchesini Sala in Vicenza were part of an immersive fresco cycle completed around 1760 and detached around 1900. Incised lines (still visible in raking light) helped to guide Tiepolo as he painted quickly before the walls’ wet plaster surface dried. Tiepolo consulted a specialist in perspective, Mengozzi, to ensure that the foreshortened depictions of architecture and sculpture aligned when one stood at the center of the room, evidence of just how site-specific such decorative programs could be.
