Sunken relief is primarily found in which type of art?

Sunken relief, a sculptural technique where the design is carved into a flat surface so that the figures project only slightly from the background, is predominantly associated with ancient Egyptian art. This method was often used in the depiction of figures and hieroglyphs on temple walls and tombs, allowing for a level of depth while also facilitating the preservation of the imagery over time, as the figures are protected from damage compared to raised relief.

The technique is closely tied to the cultural and religious practices of Ancient Egypt, where art served a significant purpose in burial rites and the depiction of deities. The careful detailing in sunken relief also demonstrates the Egyptians' sophistication in understanding form and space within their artistic expression. This makes Egyptian art the most fitting answer when considering the context and historical relevance of sunken relief.
