The Sun and the Moon on the Two Rings: The Two Old Symbols as the Two Readings of One Setting

Set two equal marked rings overlapping, as the author's instrument in Two Sliding Rings does, and the two oldest astrological symbols appear at once. The fixed ring with its center point is the Sun's symbol, and the line from that center to the sliding ring's center is twice the cosine of the setting. The crescent left where the sliding ring falls outside the fixed one is the Moon's symbol, its two horns are the two points where the rings cross, and the line between the horns is twice the sine. One setting carries both lines, and the two share one unit between them. The square of half of one plus the square of half of the other is always one, so as the rings slide the length passes from the Sun's line to the Moon's and back. The Babylonians counted in base sixty and called the Moon Sîn, drawing him as the crescent, a simple way to remember that the line between the crescent's horns is the sine. Inscribe the equilateral triangle in each ring and join the two base to base along the slide, and they form the diamond that Kelvin Abraham's Tetryonics draws for the photon. Its long diagonal, through both centers, is the Sun's line and the electric axis. Its short diagonal, between the crossings, is the Moon's line and the magnetic axis, with the crescent's two horns at the magnetic poles. The same key laid on the Earth places the lightning belt, which carries roughly 78 percent of the world's lightning between thirty degrees north and south, along the Sun's line, and the magnetic poles at the Moon's horns. New here: the two symbols identified with the two readings, the crescent's horns with the crossings, the split of one unit between the two lines, the two lines matched to the electric and magnetic characters, and the match of the photon diamond's two axes to the setting. The instrument itself is from Two Sliding Rings (Strassner 2026) and the digit checks that certify each setting are Neal's Net (Strassner 2026, V3). The photon diamond is Kelvin Abraham's Tetryonics, cited as his model. Every length and count is verified by the script in the appendix. Part of The Strassner Series: Fibonacci Geometry and Harmony.
