“Means Father or great arch. Again this connotes astrological phenomena. The great arch or arc, is the passage of the sun across the northern dome of the sky. This was revered and is why there are beautiful arches in all the cities of the world. Arches symbolize the sun’s triumphant journey. A man who measured or observed this movement was titled-Patriarch.”
