How did one recognize a Christian sarcophagus?

Question

Quizplus · Accepted Answer

Christian sarcophagi were typically decorated with scenes from the Bible or early Christian history, such as Jonah and the whale, the story of Susanna and the Elders, or the Good Shepherd. Christian symbols such as the chi-rho (☧) or the fish, which were commonly used by early Christians, might also be included in the design. These were not necessarily exclusive to Christian sarcophagi, but they were more likely to be present than on those of non-Christian owners. The name of the owner, if included, would typically be inscribed in the border or on a separate panel. The Crucifixion, while an important Christian subject, was not always depicted on sarcophagi as it did not become an established artistic convention until the late 4th century.
