 Elaborately carved marble and limestone sarcophagi are characteristic of the 2nd to the 4th centuries with at least 10,000 examples surviving. Although mythological scenes have been most widely studied, sarcophagus relief has been called the "richest single source of Roman iconography," and may also depict the deceased's occupation or life course, military scenes, and other subject matter. The same workshops produced sarcophagi with Jewish or Christian imagery.
