Elior contends that Josephus, a former Jewish priest who wrote his history while being held captive in Rome, "wanted to explain to the Romans that the Jews weren't all losers and traitors, that there were many exceptional Jews of religious devotion and heroism. You might say it was the first rebuttal to anti-Semitic literature." She adds, "He was probably inspired by the Spartans. For the Romans, the Spartans were the highest ideal of human behavior, and Josephus wanted to portray Jews who were like the Spartans in their ideals and high virtue."
Early descriptions of the Essenes by Greek and Roman historians has them numbering in the thousands, living communally ("The first kibbutz," jokes Elior) and forsaking sex — which goes against the Judaic exhortation to "go forth and multiply." Says Elior: "It doesn't make sense that you have thousands of people living against the Jewish law and there's no mention of them in any of the Jewish texts and sources of that period."
