Bulgaria’s Ancient Rock-Cut City May Have Shared Its Name with a Famous City in Anatolia
Perperikon is one of the most extensively excavated ancient sites in Bulgaria, yet archaeologists still know surprisingly little about the name its inhabitants used nearly 2,000 years ago. The city flourished during the Roman period, leaving behind monumental buildings, elaborate tombs and evidence of a prosperous community, but its identity in the written records of antiquity has remained uncertain.Book Site Tours
The answer may lie in a name recorded by the second-century geographer Claudius Ptolemy. Archaeologist Prof. Nikolay Ovcharov first proposed the identification twenty years ago, when much of Perperikon’s Roman history was still emerging from the excavations. Now, drawing on the city’s archaeological remains and a closer examination of historical maps, he argues that the evidence for his interpretation has become considerably stronger.
The earliest name Ovcharov proposes for Perperikon is Pergamon, also known as Pergamos or Pergamum. It appears in Geography, the second-century work of Claudius Ptolemy, who recorded thousands of places throughout the ancient world and attempted to locate them using geographical coordinates.
Ptolemy placed a settlement called Pergamon in Inner Thrace, but finding its exact location has proved difficult. His geographical system differs from modern maps, and distortions in the surviving coordinates have complicated efforts to match ancient settlements with present-day archaeological sites.
