ARZIGNANO, ITALY—Following clues in historic documents, archaeologists and their students from the University of Kentucky have found evidence of a Roman settlement in northern Italy, and a possible prehistoric site beneath it, using ground-penetrating radar and a magnetometer. “We had 500 years of information that was all scattered and never really put together or even looked at by scientists, which included some very detailed manuscript information by eyewitnesses who actually saw the Roman town on two different occasions when it was uncovered by flooding,” said archaeologist Paola Visonà.
