The brief Babylonian captivity of the Hebrews that began in 586 BCE opened a minor power vacuum in Judah (prior to the Judaeans' return under the Persian King, Cyrus the Great, who reigned 559–530 BCE). As Edomites moved into open Judaean grazing lands, Nabataean inscriptions began to appear in Edomite territory. The first definite appearance dates from 312/311 BCE, when they were attacked at Sela or perhaps at Petra without success by Antigonus I's officer Athenaeus in the course of the Third War of the Diadochi; at that time Hieronymus of Cardia, a Seleucid officer, mentioned the Nabataeans in a battle report. About 50 BCE, the Greek historian Diodorus Siculus cited Hieronymus in his report, and added the following: "Just as the Seleucids had tried to subdue them, so the Romans made several attempts to get their hands on that lucrative trade."
