That is a good call with the crescent moon symbolism and Mary.  I would not have thought of that, but it is indeed a common associacion.  A common Christian millenialist symbol was a circle with a crescent moon along one side, a cross at the bottom and an interlocking AM that could easily be mistaken for a geometric design.   The AM stood for Ave Maria, or more secretly, Ave Milleniarum.
