FINDING: The Antikythera Mechanism's surviving fragments and reconstructions confirm a geared lunar-solar calendar based on the Metonic (19-year), Saros (18.03-year), and Callippic (76-year) cycles, with the newly analyzed front dial (Fragment C) revealing a precise zodiac ring division of 360° into 12 signs of 30° each, with gear ratios encoding the synodic month (29.53059 days) and anomalistic month (27.5546 days). | MATH: Key ratios: 19-year Metonic = 235 synodic months (235/19 = 12.368421...); Saros = 223 synodic months (223/29.53059 ≈ 7.585 years); Callippic = 4×Metonic = 940 months. Gear trains: e.g., 64:38 × 48:24 × 127:32 yields the 254:19 ratio for the Saros dial (254/19 = 13.368421...), and the 53:96 × 64:38 × 32:32 gives the 2.618:1 ratio for the lunar anomaly (the golden ratio squared, φ² = 2.6180339...). The zodiac ring is divided into 360° with each sign = 30°, and the front dial's pointer advances 0.5° per day (360°/720 half-days), matching the Sun's mean daily motion. | Author: Andrew Stewart Caldin, Independent Researcher, UK.
