Virgin Mary Standing on a Snake.

As I explained with the Rod of Asclepius the Biblical snake represents the Sun moving on its ecliptic, its path, which makes a Sine Wave shape. A Sine Wave looks like a snake!

Virgo is represented as the Virgin, this has more to do with the place the Chrism Seed is born. The solar Plexus. The seed is born of a pure (virgin) body (aka healthy body, the worthy-Ship.

But the figure of mary standing on a snake is the Analemma because it makes the shape of a woman in the sky. (analemma mini series). This is also referenced in Revelation 12:1--A woman clothed by the sun=Analemma. 12 stars upon her head are the 12 signs on the Sine Wave.

As the sun goes around, it make the A-line skirt shape. Or like a tee-pee. Or Christmas tree. "Clothed by the Sun"

The Analemma are references points ON the Sine Wave (snake) making a figure 8 like the shape of a woman's body.

The 12 Signs (sine) are on the wave, SunSon's path, and the Snake represents the movement of the Sun on that path.
