Among the most significant finds is a third-century fresco discovered in the western Turkish city of Iznik, depicting Jesus as the Good Shepherd. Archaeologists say the painting ranks among the oldest known images of Christ as an adult and is exceptionally well preserved due to its location inside a sealed, oxygen-depleted family tomb.

The fresco, which dates to the early-to-mid third century, depicts Jesus with short hair and without a beard, dressed in Roman-style clothing. Researchers say the preservation of the artwork provides an unusually detailed look at how some early Christians may have envisioned Christ nearly 1,800 years ago.
