Did Pompeii Know the Cross? Rethinking Its Mosaics

The most amazing thing about Pompeii is the preserved mosaics that give us insight into 1st-century art. Many of the patterns endure over centuries, but some of these early patterns hint at a Christian following. We can see the cross in stone on our walking tour. Let’s explore the cross-like designs in the Pompeii archeology park.

The Cross in Stone

We happened upon a small room in a rich person’s house that told the story of Christianity. As we entered the back courtyard, no name was given to the location. We just thought it was another house, but the whole block was the home. This was the Casa de Forno, also known as the House of Fauno. Two atriums exist in the house, and a more public one exhibits the second-century BC mosaic of Alexander the Great and Darius III. Yet, in the far back room, near the back entrance, is a room that is without a doubt set for a Christian.

The initial mosaic is the cross, and the rest of the room features X-shaped symbols that, in Greek, stood for Christ. How can this not be anything but a room set aside for either a house church or a devotional purpose? The room is quite small, so it can only host a few people. Was that the early church in Pompeii?

To find these places, check out my walking map, which shows the locations of these sites.

Casa del Cinghiale – Entry cross-design mosaics

The entryway of Casa Del Cinghiale (Address: #8, Via Dell’Abbonda Street) is filled with cross-like mosaics. The day we visited, the house was closed, and it was most likely part of the rotation of houses they open on certain days. It looked like renovations were underway at this residency in March of 2026.

Early Greek designs focused on 4-petal displays that highlighted a flower or star more than a cross, but these images later dominated Christian religious sites. Here, a nod to these designs enhances this entryway. At the doorway entrance, there is a marble centerpiece that most likely enabled a closed door to this entry, so these designs would be viewed only upon entering the house.

Also, the upper four images feature two cross designs and an interlocking figure-eight design, which later became an eternal symbol in mosaics. See the Zeytinburnu Mosaics. These upper designs seem to promote a simple cross in stone.

The cross designs here are later found in churches within the Western and Eastern Roman Empires. Could some of these early believers, as craftsmen, form early cross-like templates that were copied throughout the empire? These designs convey a double meaning: the Greek cross-like patterns that predate Christianity, and the coming cross-like patterns that will affirm Christianity’s influence. During the first five centuries of Christianity, believers loved the cross, and this became an early mosaic style, with differing types of crosses patterned in design by at least the 5th-century AD.

In Casa del Frutteto, the octagonal shape at (here points) became a dominant feature in 5th- and 6th-century Byzantine churches. Here, this early pattern centered on an entry in Pompeii. Later, the cross overlapped with the Greek “X”, which depicted the cross of Christ.

Early Basic Mosaic Patterns of the 1st-century

In my observations, I noticed some basic black-and-white tiles without patterns or images, as well as some simple tiles with inlaid white stones. These basic mosaics, which I have named as such, seem like earlier mosaics that most likely date to the early 1st century or earlier. Their dominance in some homes gives the impression of an earlier design, often to enhance the wall frescoes.

In the house of the Dioscuri, we see some of these early designs, as well as Roman images of Castor and Pollux, the twin sons of Zeus and patrons of sailors. These are mentioned as symbols on a boat that the apostle Paul sailed on, heading to Rome, in Acts 28:11. I observed how mosaics enhanced the wall frescoes and the image of what is most likely Castor with a horse at the entrance. Why did the book of Acts mention these gods right after a shipwreck? We know God protected Paul, but these images and superstitions dominated the ancient world, as this house demonstrates. Maybe the gospel reached specifically into this world, so Luke mentions the boat.

These homes promoted diverse beliefs, and the video below will help in understanding the role of mosaics in a home.

The homes that display these 1st-century mosaics give us much to think about, and I visited only about half of them. Are there more there for discover on a visit? If you see more, please let me know so I can add them to this amazing walking tour.

We know that the Scriptures state, “For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.” (1 Corinthians 1:18, ESV). For these early believers, the cross centered their faith. They looked to it for hope and the answer to eternal life. The main symbol they promoted was the cross, so it is not surprising to find elements of it in this destroyed 1st-century city. In the next article, we will see the cross prominently displayed among the Roman gods.
