FINDING: Babylonian tablet Plimpton 322 is a pre-calculated trigonometric table using base-60 sexagesimal ratios, not angles. | MATH: Tablet lists 15 rows of Pythagorean triples (a² + b² = c²) in base-60; ratios b²/(c² - b²) or (c² - a²)/a² yield exact sexagesimal fractions. Key constants: 1;59,15, 1;56,56,58,14,50,6,15 (base-60). No explicit angles, but ratios correspond to sec²(θ) or tan²(θ) values. | CONNECTION: Base-60 division of circle (360° = 6×60) directly links to geometric harmony; ratios approximate 0.618 (1/φ) and 1.618 (φ) in some triples. Tablet uses unit circle radius = 1 in base-60, prefiguring modern trig. | DEPTH: 8 — Profound because it shows Babylonians understood Pythagorean triples as exact ratios, not approximations, and used base-60 for precise computation 1000 years before Greeks. This implies a sophisticated geometric worldview where circle division and right-triangle ratios were foundational, aligning with later harmonic principles (φ, 0.618, 0.382).
