Let us now listen now to Philo: "The raiment of the priest is altogether a representation and imitation of the universe, and its parts are the parts of the other. His tunic is all of blue linen, the symbol of the sky. [The rabbis had a similar fancy of the Tsitsith (fringes).] And the flowers embroidered thereon mark the earth, from which all things flower. And the pomegranates are a symbol of the water, being skilfully called thus ([Greek: rhoischoi], _i.e._, flowing fruit) because of their juice, and the bells are the symbols of the harmony of all the elements."[325] It is true that the symbolism of two allegorists is varied, but a common spirit and aim underlie their interpretations. This is true alike of their account of the ritualistic and civil law of Moses. Either, then, there was a common source of Jewish apologetic literature, or Josephus must have borrowed from Philo. It is significant that he is the only contemporary of Philo that mentions him. He speaks of him as a distinguished philosopher, the brother of the alabarch, and the leader of the embassy to Gaius.[326] He knows also of the anti-Semitic diatribes of Philo's great enemy Apion, and two of his extant books are masterly reply to their outpourings. Hence it is not rash to assume that he knew at least that part of Philo's work which had a missionary and apologetic purpose--the "Life of Moses" and the "Hypothetica." He makes no acknowledgment to them, it is true, but expressions of obligation were not in the fashion of the time. Plagiarism was held to be no crime, and citation of authorities in notes or elsewhere was almost unknown in literature--save in the Talmud,[327] where to tell something in the name of somebody else is a virtue. But one can hardly doubt that the man who devoted himself to refuting the lying calumnies of Apion first made himself master of the classical work of Apion's opponent, which claimed to give to the Greek world the authoritative account of the Jewish lawgiver and his legislation.
