@Sree I can try. Thanks for the opportunity.
First of all I would clarify that I didn’t say he was not crucified, but rather, that he didn’t die on the cross. Crucifixion, historically, means to fasten someone to something. So in mythology Prometheus, for example, is pictured or written to have been crucified or fastened to the earth or specifically, rock. The illustration of Justus Lipsius given here has two examples, one being the traditional cross of Jesus and the other a simple stake. The Romans, over time, used many shapes. The X shape, t shape, a simple stake etc. They crucified a lot, so it isn’t very likely they used two pieces of timber in an area where trees were not exactly plentiful.
The Bible uses variations of the Greek word stauros, translated into the Latin crux, both which can mean a cross of any shape, but more likely a simple one piece stake. However, the Bible also uses the term xylon, which doesn’t mean a cross but only a single piece of wood. The cross didn’t appear in Christian burial monuments etc. until after Constantine, who was a sun worshiper of the phallic idol himself, and that for political reasons.
“The shape of the [two-beamed cross] had its origin in ancient Chaldea, and was used as the symbol of the god Tammuz (being in the shape of the mystic Tau, the initial of his name) in that country and in adjacent lands, including Egypt. By the middle of the 3rd cent. A.D. the churches had either departed from, or had travestied, certain doctrines of the Christian faith. In order to increase the prestige of the apostate ecclesiastical system pagans were received into the churches apart from regeneration by faith, and were permitted largely to retain their pagan signs and symbols. Hence the Tau or T, in its most frequent form, with the cross-piece lowered, was adopted to stand for the cross of Christ.”—An Expository Dictionary of New Testament Words (London, 1962), W. E. Vine, p. 256.
“Various figures of crosses are found everywhere on Egyptian monuments and tombs, and are considered by many authorities as symbolical either of the phallus [a representation of the male sex organ] or of coition. . . . In Egyptian tombs the crux ansata [cross with a circle or handle on top] is found side by side with the phallus.”—A Short History of Sex-Worship (London, 1940), H. Cutner, pp. 16, 17
“Various objects, dating from periods long anterior to the Christian era, have been found, marked with crosses of different designs, in almost every part of the old world. India, Syria, Persia and Egypt have all yielded numberless examples . . . The use of the cross as a religious symbol in pre-Christian times and among non-Christian peoples may probably be regarded as almost universal, and in very many cases it was connected with some form of nature worship.”—Encyclopædia Britannica (1946), Vol. 6, p. 753
