If such a person as Jesus of Nazareth ever lived and was ever executed by the Romans, it is very probable that he was hanged, and the gallows may, very likely, have been of a form similar to that of a rude cross. The term crucifixion does not necessarily imply that one must be nailed outspread upon a symmetrical cross. It was the ancient custom to use trees as gibbets for execution, or a rude cruciform gallows, often called a "tree" (Deut. xxi, 22, 23; Nicodemus ix, 10). To be hung on such a cross was anciently called hanging on a tree, and to be hung on a tree was crucifixion. This rough method of execution was later modified by the Christians to the present theory of the crucifixion, as they very naturally desired to appropriate the cross for their own especial emblem, owing to the fact that its great antiquity as a universal religious symbol would aid in the propagation of their faith, and since its earliest inception, Christianity has been ever prone to aid its proselyting by the adoption of pagan dogmas, symbols and practices from the so-called heathen theologies. Of all religious symbols, the cross is the most ancient and sacred. It has from the earliest antiquity been the mystic emblem for reverence and awe, and appears to have been in the aboriginal possession of every ancient people. Populations of essentially different culture, tastes, and pursuits have vied with one another in their superstitious adoration of it. Greek crosses of equal arms adorned the tomb of Midas of Phrygia; and long before the time of the Eutruscans, the inhabitants of northern Italy erected crosses over the graves of their dead. The cross was common to Mexico; white marble crosses were found on the island of Saint Ulloa by its discoverers; and it was greatly revered in Paraguay and Peru. While the origin of the cross, shrouded as it is in the mists of the remotest antiquity, has been the subject of much speculation which has resulted in numerous theories, it is, undoubtedly, a conventionalized result of primitive phallic ideas. Sexual motives underlie and permeate all known religious systems. The idea of a creative god naturally gave rise to characteristic symbolical expression of the male and female principles, which were gradually modified and reduced to the tau (a Gothic T), representing the male principle, and the ring, representing the female principle. As a complete expression of the creative power, these two symbols were often placed in conjunction; and the most ancient form of the conjunction was, probably, that of the crux ansata, known to the Egyptians as "the emblem of life," which was very simply formed by placing the ring above the T. This emblem is sometimes called the "cross with the handle," because in ancient sculpture it is often represented as being carried by the ring. (See Doane, "Bible Myths"; Inman, "Ancient Faiths," etc.). This handled cross was also sacred to the Babylonians and occurs repeatedly on their cylinders, bricks and gems.
