This sketch shows a corner of an ornate church interior. Two tall columns stand side by side, their tops carved with swirls and leaves. Between them, a narrow window has a painted frame with curved shapes and soft colors—pinks, greens, and yellows. The walls and ceiling are covered in detailed patterns, like lace or honeycomb, with arches leading deeper into the space. The artist used light washes of color to suggest shadows and depth, making the stone look real. Notice how the window’s colors fade slightly, like sunlight dimming through glass.
