It was a perfect Israeli day. My friend Udi Levy and I meandered in the warm sun through an ancient Nabataean city, Shivta, 30 acres of archaeological paradise in the Negev Desert. Udi, who wrote The Lost Civilisation of Petra about the Nabataeans who flourished around the time of Christ, rhapsodised about Shivta's churches, perhaps the oldest in Christendom, palaces and wine presses. "The fact that Shivta is out of reach," he said, remembering we were in the middle of an Israeli artillery firing range 50 miles south of Beersheva, "is why it was never conquered throughout its history. It's unique." So too was our day, far from the conflict between Israel and the Palestinians.
