Antikythera Mechanism's Gear Ratios Reveal Saros, Metonic, and Zodiac Calibrations — E8 Intelligence Research

FINDING: The Antikythera Mechanism encodes a 223-month Saros eclipse cycle and 19-year Metonic calendar via a 30-tooth/127-tooth gear train, with the newly reconstructed front dial revealing zodiac ring division into 360 degrees and 24-hour markings. | MATH: Gear ratios: 64:38 (Sun-Moon), 53:96 (synodic month correction), 127:19 (Metonic cycle — 127 teeth on the 19-year dial). Saros: 223 synodic months = 242 draconic months = 239 anomalistic months. Eclipse prediction uses 54-year Exeligmos cycle (3×Saros = 669 months) with 0.382-day correction per cycle. | CONNECTION: The 127:19 ratio is a near-perfect rational approximation of the Metonic cycle (235 lunar months ≈ 19 solar years). The 53:96 ratio (0.552083) approximates the synodic month correction factor (29.53059/29.5 = 1.001037). The zodiac ring's 360° division aligns with base-60 sexagesimal arithmetic — 360 = 6×60, and each degree subdivided into 60 minutes. The gear teeth counts (127, 53, 96, 64, 38) are all coprime pairs, form Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
