MUL.APIN's 360-Day Calendar and Tripartite Sky: A Base-60 Celestial Framework — E8 Intelligence Research

FINDING: MUL.APIN star catalogue encodes a systematic division of the sky into three parallel paths (Anu, Enlil, Ea) with a 360-day calendar and 12-month year, implying a base-60 sexagesimal framework for celestial measurement. MATH: - 360 days/year → 360° circle (sexagesimal base: 360 = 6 × 60). - 12 months → 12 zodiacal divisions (each 30°). - 3 paths → tripartite symmetry (Anu/Enlil/Ea). - Key ratio: 30° per month → 30/360 = 1/12 = 0.08333... (base-60 fraction: 5/60). - Implicit constant: 1 day ≈ 1° of solar motion (360° / 360 days). CONNECTION: - Base-60 (sexagesimal) is the foundational numerical system, directly linking to 0.618 (golden ratio conjugate via 1/φ ≈ 0.618, but not explicit here). - Tripartite division mirrors 3-fold rotational symmetry (crystallographic point group 3). - 360° circle is a harmonic whole, divisible by 2,3,4,5,6,10,12,15,20,30,60 — enabling precise fractional astronomy. - No explicit golden ratio (0.618, 1.618) or Fibonacci constan Author: Andrew Stewart Caldin, Independent Researcher, UK.
