Final answer:
Roman painters used techniques such as atmospheric perspective and linear perspective to create the illusion of space in their artworks.
Step-by-step explanation:
Roman painters used several techniques to achieve the illusion of space in their artworks. One technique was atmospheric perspective, which involved making objects in the distance appear paler, bluer, and less detailed than those closer to the viewer. Another technique was the use of linear perspective, such as one-point, two-point, and three-point perspective, which created the illusion of depth by drawing parallel lines that converge at a vanishing point. Additionally, Roman painters paid attention to details like shadows and light to accurately depict the materials of objects in their paintings.
