WARSAW, POLAND—A large, first-century bathhouse is being excavated at Apsarus, a Roman fort located in Georgia on the Black Sea, by a team of archaeologists from the University of Warsaw and the Gonio-Apsarus Museum and Sanctuary. They have recently discovered a mosaic featuring geometric designs that had been installed over a heated floor. “Although many floor mosaics have been discovered in the countries around the Mediterranean, the Gonio find should be regarded as exceptional. It is one of the few examples of discovery of a luxury finish flooring in a bath house built by the army for its own needs,” Radoslaw Karasiewicz-Szczypiorski told Science & Scholarship in Poland.
