In this article we will continue our discussion of the Platonic solids by moving into the topic of duals and the sacred number canon.

We first discussed the sacred number canon way back in Article 4.  The Sacred Number canon deals with numbers that are significant geometrically and astronomically.  This means that the numbers are associated with angles of the Platonic solids and astronomical cycles such as the Precession of the Equinoxes.

# Platonic Solid Duals

Duals are two polyhedra whose faces and vertices correspond perfectly.

This illustrates the Principle of Inversion.

As a Platonic solid oscillates it can turn inside out.

To find the dual:

• Define the midpoint of each edge. Connect the points in 3D space.
• Or join the face centers:  To do so, define the midpoint of each face.  Connect the center of each face with a line.

The following are duals:

• Octahedron and Cube

• Icosahedron and Dodecahedron

“Not only does the projection of the internal radii of the icosahedron form the edges of the dodecahedron but reciprocally the projected radius of the dodecahedron produces the edges of the icosahedron.  This alternating projection of one form out of the other is only graphically indicated here, but is geometrically a fact.”1

• Tetrahedron is its own dual (self-dual).

• Only the tetrahedron is its own dual. When it merges with its dual it forms a star tetrahedron (a.k.a. the stellated octahedron, pictured below)

Duals can be married with their edges touching at their midpoints to create compound polyhedra:

• Star Tetrahedron – This creates a stellated octahedron from two tetrahedra.  This is the balance of two tetrahedra.

• Cuboctahedron (vector equilibrium) – Balance of the cube and octahedron.

• Icosidodecahedron – Balance of the icosahedron and dodecahedron.

# The Platonic Solids and the Four Elements

As we saw in earlier articles, the sum of the angles of the four Platonic solids that represent Fire, Air, Earth & Water (the 4 Earthly Elements) equals the diameter of the Earth in miles (99.97% accuracy).

Earth’s polar diameter in 2013 (NASA) = 7899.86 miles

The equatorial diameter = 7926.33 miles

The diameter from tropic of Cancer to tropic of Capricorn = 7920 miles

Sum of the angles of the tetrahedron, cube, octahedron, icosahedron (the 4 elements) = 7920º.

Note that these numbers are always in flux due to seasonal, lunar, meteorological, and geological changes.

The Sum of the Angles of the Cube (2160°) = the diameter of the Moon in miles (99.99% accuracy).

2160 = the diameter of the Moon AND the length of 1 “Great Month” in the 25,920 year cycle of the Precession of the Equinoxes.

Time AND Space are determined by Geometry – and not just any Geometry, Platonic Solid geometry.

The sum of the angles of the tetrahedron (fire), octahedron (air) and dodecahedron (Aether/spirit) = 8640°.

8640 x 100 = 864,000 miles = the diameter of the Sun (99.95%)

# Precessional Numbers & Platonic Solids
