(July 3, 2022) The Gateway Star symbol is composed of two intertwined triangles. The triangle has been a symbol for a door or gateway since the first alphabet. It is one of the earliest representations of the letter "D" which originated from the Akkadian word "daltu" meaning "door." The Greek letter "delta" is also a triangle.
The gateway star is the union of two doorways. The upside down triangle comes from the female pubic triangle which typically represents mother earth. The right-side up triangle represents the masculine Divine realm. Thus their union forms the gateway to the life-growth powers of the Ancient Pagan Paradigm. Yahweh belongs to this class. (contrast this to the Pentacle which is the gateway for the motion powers).
During the late 1600's the Gateway Star started to be placed on synagogue walls in Europe during a revival of Jewish mysticism. Only then did it start to be called the "Star of David" or "Shield of David" by those unaware of its mystic significance. In 1897, with the intertwining of its lines eliminated, it was chosen as the central symbol on a flag at the First Zionist Congress.
