MUL.APIN Star Catalogue: Sexagesimal Math Encoding 360-Day Year and 30° Intervals — E8 Intelligence Research

FINDING: MUL.APIN star catalogue contains systematic star lists organized by paths of Anu, Enlil, Ea, with mathematical intervals and period relations. | MATH: The catalogue uses base-60 (sexagesimal) numerical system; star risings and settings are spaced at intervals of 30 days (1/12 year) and 60 days (1/6 year), reflecting 360-day ideal year; celestial periods encoded as 360 (days), 12 (months), 30 (days per month). | CONNECTION: Base-60 directly relates to 360° circle; 30° intervals correspond to zodiacal divisions; ratio 30/360 = 0.0833, 60/360 = 0.1667; no explicit golden ratio or Fibonacci constants found in these summaries. | DEPTH: 4 — foundational for ancient astronomical mathematics, but no new harmonic or crystallographic constants extracted from provided sources.
