I believe the correct answer is high relief.
When a sculpture is designed to be viewed from one side, and
protrudes dynamically from its background plane (at least half of their natural
circumference of sculpture must protrude from background plane) or is carved with
deeply incised marks is called high relief. For example, high-relief art was
made with marble by Francesco Grassia in Rome.
The title of this example of art is Sarcophagus of the church of Santa Maria Antiqua.
It does contain Christian symbolism that was unrecognizable by pagans. It was also possibly made to be the tomb of a rich Christian living in the third century. It was made in 275 CE and contains the representations of many Biblical and non-biblical people.
