The chilly December wind whipped rain across the strewn wreckage of a city that, nearly 3,000 years ago, ruled almost the entire Middle East. Rivulets of water ran through the dirt, washing away chunks of ancient stone. The city of Nimrud in northern Iraq is in pieces, victim of the Islamic State group's fervor to erase history. The remains of its palaces and temples, once lined in brilliant reliefs of gods and kings, have been blown up. The statues of winged bulls that once guarded the site are hacked to bits. Its towering ziggurat, or step pyramid, has been bulldozed.
