Archaeologists in Istria, Croatia, have re-exposed remarkably preserved Christian mosaics dating back to the 5th century. The site, of ancient significance, yielded mosaics adorned with geometric and floral designs. Unusually, an inscription reveals the names of the donors who funded the building's construction. The couple identified themselves as "great sinners," a highly atypical dedication for the period. This self-description offers a fascinating insight into early Christian beliefs and practices concerning repentance and faith. Researchers believe the mosaics were part of a larger complex, potentially a church or baptistery, and are continuing to excavate the area for further discoveries. The find contributes significantly to understanding the religious and artistic heritage of the region.
