On the origin of the LXX, see above, Bk. V. chap. 8, note 31. The mythical character of the common legend in regard to its composition is referred to in that note, and that the LXX (or at least that part of it which comprises the law) was already in existence before the time of Aristobulus is clear from the latter’s words, quoted by Eusebius, Præp. Evang. XIII. 12, 1–2 (Heinichen’s ed.).
