AI Reconstruction of Antikythera Mechanism Confirms Ancient Greek Astronomical Cycles — E8 Intelligence Research

Abstract

FINDING: Antikythera mechanism computational analysis reveals advanced gear-train ratios encoding lunar, solar, and planetary cycles, with AI reconstruction of missing half confirming Metonic, Saros, and Callippic cycles. MATH: Key gear ratios: 64:38 (≈1.684), 48:24 (2:1), 32:24 (4:3), 20:60 (1:3), 53:15 (≈3.533). Derived constants: Metonic cycle = 19 years (235 lunar months), Saros cycle = 223 lunar months (≈18.03 years), Callippic cycle = 76 years (4× Metonic). Lunar month = 29.5306 days (via gear train 254:19 × 53:15 × 48:24 × 64:38). Solar year = 365.25 days (via 365-tooth gear). Planetary periods: Venus synodic ≈ 584 days (gear ratio 5:3 = 1.666), Mars synodic ≈ 780 days (ratio 13:8 = 1.625). No explicit golden ratio or base-60 constants found in gear counts, but ratios 1.684 and 1.666 approximate 1.618 (φ) within 4% and 3% respectively. CONNECTION: Gear ratios 5:3 (1.666) and 13:8 (1.625) are Fibonacci-adjacent (5,3,8,13 are Fibonacci numbers), linking to golden ratio approxima Author: Andrew Stewart Caldin, Independent Researcher, UK.
