KARDZALI, BULGARIA—Excavation of a Christian bishop’s residence dating to the early fifth century A.D. continues in southern Bulgaria’s ancient Thracian city of Perperikon, according to Archaeology in Bulgaria. The residence was part of a 70-foot-long basilica. “This is one of the earliest ensembles [of religious Christian buildings] in all of early Christian Europe,” said archaeologist Nikolay Ovcharov. The front piece of a bronze engolpion cross, complete with depictions of the crucified Christ figure and the four Christian saints known as the Evangelists, was found within the building. Such crosses were designed to be worn on the chest, suspended by a chain, and are now worn as a symbol of a bishop’s rank. This cross, dated from the tenth to twelfth centuries A.D., may have held relics of a saint. Ovcharov thinks the well-worn cross may have been worn for more than 100 years, since the faces of its figures are worn off. To read about another recent discovery in Bulgaria, go to “Mirror, Mirror.”
