Ur-Nammu's ziggurat to Nanna, the moon god, is the best preserved of Mesopotamia's temple-mountains: a mudbrick core faced in baked brick set in bitumen, with three staircases converging on a summit shrine now vanished. Ziggurats were literal 'mountains of god' for a land without mountains, and their stepped form is the deep ancestor of the pyramid idea. Woolley's excavations nearby uncovered the Royal Tombs and their retinues of sacrificed attendants; tradition ties Ur to Abraham's birthplace.
