Thanks a lot for your answer! I've understood your points. I've collected material for my article in russian about cross/stake, which consists of more than 700 files (article, pics and so). But as I remember I there is no quatations from "Philo, Xenophon and Josephus" concerning the matter. When I tried to find such a evidence in Google it gave only link to anti-JW sites. Can you help me a little bit more with that referencies, please? )
