MEGIDDO, ISRAEL—According to a Live Science report, archaeologists from the Jezreel Valley Regional Project have uncovered walls of an amphitheater at Legio, a site south of Megiddo in Israel that served as a Roman military base for some 5,000 soldiers in the second century A.D. Using ground-penetrating radar, the team identified a cemetery and traces of a building outside the legionary camp's walls. Subsequent excavations exposed circular stone walls with remnants of blood-red paint that belonged to the amphitheater, which was used for military combat training. "This kind of amphitheater — for the army, not the general public — has not been found before in the region," said archaeologist and project co-director Matthew J. Adams. Lamps and other artifacts found within the gate of the structure may be evidence of the cult of Nemesis, the goddess of retribution, he concluded.
