Architectural Drawing: 'Le Nouvel Opéra de Paris' - Dome and Pavillon

This item is an aged architectural drawing, notably a blueprint or detailed rendering, illustrating 'Le Nouvel Opéra de Paris,' specifically focusing on the dome and one of its pavillons (pavilions). The drawing is executed on what appears to be heavy paper or vellum, softened and discolored over time to an off-white or light cream hue. The primary medium is likely ink, presenting fine lines and intricate details in shades of grey and black, typical of late 19th-century architectural representations. The sheet displays visible signs of age, including overall yellowing, faint smudges, and possibly some foxing or minor staining, indicated by slight variations in color saturation and subtle blemishes across the surface. A prominent horizontal fold or crease is visible across the middle, suggesting it may have been folded for storage. There are also some subtle reflections and variations in lighting across the image, hinting at a protective frame or glass covering, though this isn't explicitly visible. The drawing features two main detailed views of the Opera Garnier structures. The upper image depicts the intricate dome, crowned with an ornamental structure and adorned with decorative elements such as cartouches and sculptural figures. The lower image presents a detailed side view of what appears to be a pavillon or an elaborately decorated section of the building's facade, complete with columns, arched windows, and a highly ornate upper section. Smaller, less detailed sketches or sections are included around the main renderings, likely illustrating specific architectural elements or details. The overall style is characteristic of Beaux-Arts architecture, emphasizing classical forms, elaborate ornamentation, and meticulous detail. The craftsmanship of the drawing itself is exemplary, with precise linework and shading effectively conveying three-dimensional form and texture. The title 'LE NOUVEL OPÉRA DE PARIS' is clearly visible at the top, along with other French annotations that further specify the depicted sections, such as 'DÉTAILS DU PAVILLON LATÉRALE' (Details of the Lateral Pavilion) at the bottom. The contextual information about this being an 'Opera Garnier blueprint' strongly supports the identification as a drawing related to the construction or design of the Palais Garnier, which opened in 1875. This suggests an estimated age of mid to late 19th century.
