When archaeologists from the University of Chicago began major excavations at the important Biblical site of Megiddo in the 1920s, they came across this 15-inch stone fragment from a previous excavation’s dump carved with cartouches of Pharaoh Sheshonq I. The fragment, originally part of a 10-foot-high victory stela erected by the pharaoh, confirms that Sheshonq invaded northern Israel and sacked Megiddo, just as he claims in the Bubastite Portal relief.
