This image depicts the interior of the Chiesa di San Martino (Church of Saint Martin) in Ferrara, Italy, viewed from a nave or side aisle looking towards the main altar. The central focal point is a large, ornate altarpiece featuring an arched-top oil painting, *The Vision of Saint Bruno* by Guercino, set within a prominent golden frame. The painting shows multiple figures, including angels and a saint, illuminated by a light source depicted in the upper left. Below the painting, a marble altar table is covered with a white cloth over a dark red frontal. Four tall, golden candlesticks with white candles and one shorter candlestick are arranged on the altar table. A dark wooden lectern or stand is positioned directly in front of the altar table. The church interior is characterized by tall, dark-toned walls adorned with pilasters and moldings. Above the altarpiece, an octagonal stained-glass window displaying blues, reds, and yellows is set high in the arched wall. Protective netting is visible across the vaulted ceiling above. On either side of the altarpiece, vertical niches house statuary. Gold trim highlights architectural elements and frames. To the far right, a four-lobed decorative element is visible on the wall. In the left foreground, a dark wooden confessional booth or large pew partially obscures the view, featuring carved details and a rectangular panel. Above and to the left of this structure, a white marble sculpture of a cherub or putto is mounted on the wall. The floor is covered with a geometric pattern of light and dark tiles. On the right side of the image, several dark wooden chairs are arranged along a wall, and two lower, red-draped wooden structures flank the main altar. The scene is dimly lit, with specific illumination on the altarpiece and the stained-glass window. No individuals are present.
