Step-by-step explanation:
The painting shows effective use of light and shadow to create a sense of three-dimensional form and to shape viewers' perceptions. Artists strategically use light to direct attention, create a mood, or communicate a message with their artwork.
For example, in a mosaic depicting horses and soldiers, the shading and play of light reflect the original painting's use of light and shadow to create a realistic, three-dimensional space. The careful shading within the mosaic tesserae gives the figures mass and volume.
In another painting, the artist uses light to strike the subject from the left, casting her right side in shadow. The folds of her sleeve demonstrate the skillful illusion of space, making it seem like there is depth on the flat canvas.
