See Negev, “Die Nabatäer,” Antike Welt, supp. to vol. 7 (1976), pp. 1–80; “The Nabataeans and the Provincia Arabia,” Aufsteig und Niedergang der römischen Welt vol. II no. 8 (1977), pp. 520–686; “Petra,” in Encyclopedia of Archaeological Excavations in the Holy Land, vol. IV (New York: Simon & Schuster, 1993); “Nabatéens et Byzantins au Negev,” Le Monde de la Bible 19 (1981). It is important, however, not to oversimplify Negev’s very important contributions to Nabataean studies, and his theories regarding the relationship between Petra and the Nabataean sites of the Israeli Negev.
