What is a characteristic of bas-relief sculpture?

Bas-relief sculpture is characterized by its shallow depth, meaning it has very little projection from the background. This type of sculpture is typically created by carving figures that stand out only slightly from a flat surface, allowing the details to be seen from the front but not from the sides.

The limited depth allows for a blend of two-dimensional and three-dimensional qualities, making bas-relief effective for decorative purposes, as seen in architectural friezes and coins. The subtlety of the projection enhances the visual impact while maintaining a connection to the flat surface, which is a defining feature of this style.

Other options describe different techniques or forms. For instance, significant projection from the background is characteristic of high relief sculptures, while a flat painting represents a completely different medium that lacks three-dimensional elements. Additionally, while bas-relief has three-dimensional aspects, the term itself specifically refers to its shallow nature rather than a full three-dimensional form.
