Theatre or theater is a collaborative form of fine art that uses live performers, typically actors, to present the experience of a real or imagined event before a live audience in a specific place, often a stage.
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.
