What better memorial to war than the cross–the hilt of the sword. The cross has long been the symbol of death particularly since Christianity decided on the impaling Jesus upon the cross; the primordial origin of the cross is in the planet Mars the god of war to whom Rome who lives by the sword prayers.
The Cabala explains how the upper three Sefirot/Luminaries of the Tree of Life corresponding to the two hemispheres of the brain plus the third eye did not break when the vessel of Tohu, the previous world broke and each of the seven remaining sefirot lined up one behind the other.
The animal derives from Tohu where the seven emotions lined up one behind the other and therefore all animals mate from the back–only the human being mates face to face. By connecting the dots of the triangle of the head the form of a serpent arises.
The cross is the most anti-Semitic symbol in the world portending to a vicious story that never happened–Jesus crucified on the cross; it is the lie which is the crux of religion causing war throughout the world.
