Step-by-step explanation:
The best definition of sunken relief is a carving in which the main figures are lower than the background. In sunken relief, the design is incised into a flat surface, and the background is carved away, leaving the main figures raised. This technique creates a sense of depth and dimensionality in the artwork. An example of sunken relief can be seen in the ancient Egyptian artwork, particularly in the carvings on temple walls and tombs.
