IZNIK, Turkey (AP) – Archaeologists in Turkey have uncovered one of the most important finds from Anatolia’s early Christian era: A fresco of a Roman-looking Jesus as the “Good Shepherd.”

The painting was discovered in August in an underground tomb near Iznik, a town in northwestern Turkey that secured its place in Christian history as the place where the Nicene Creed was adopted in A.D. 325. Pope Leo XIV recently visited the town as part of his first overseas trip.

At the time, the region was part of the Roman Empire, and the tomb in the village of Hisardere is believed to date to the third century, a time when Christians still faced widespread persecution.

The Good Shepherd fresco depicts a youthful, clean-shaven Jesus dressed in a toga and carrying a goat across his shoulders. Researchers say it is one of the rare instances in Anatolia where Jesus is portrayed with distinctly Roman attributes.

Before the cross was widely adopted as Christianity’s universal symbol, the Good Shepherd motif played a key role in expressing faith, indicating protection, salvation, and divine guidance.

Despite its central role in early Christianity, however, only a few examples of the Good Shepherd have been found in Anatolia and the one in Hisardere is the best preserved.

The Associated Press was the first international media organization granted access to the tomb. Lead archaeologist Gulsen Kutbay described the artwork as possibly the “only example of its kind in Anatolia.”

The walls and ceiling of the cramped tomb are decorated with bird and plant motifs. Portraits of noble men and women, accompanied by slave attendants, also decorate the walls.

Eren Erten Ertem, an archaeologist from Iznik Museum, said the frescoes showed “a transition from late paganism to early Christianity, depicting the deceased being sent off to the afterlife in a positive and fitting manner.”

The excavation uncovered the skeletons of five individuals, anthropologist Ruken Zeynep Kose said. Because of poor preservation, it was impossible to determine the ages of two of them, but the others were two young adults and a six-month-old infant.

Pope Leo XIV visited Iznik last month to mark the 1,700th anniversary of the Council of Nicaea that produced a creed, or statement of faith, that is still recited by millions of Christians today.

Joined by patriarchs and priests from the Eastern and Western churches, Leo prayed that Christians might once again be united.

Turkish President Recep Tayyip Erdogan, presented a tile painting of the Good Shepherd discovery to Leo during his visit.

Anatolia witnessed pivotal moments in Christian history: Saint Paul was born in Tarsus, Saint John spent his final years in Ephesus, and the Virgin Mary may have lived her last days near the same city.
