Ancient people, before telescopes, could have determined
basic astronomy constants by counting and thinking.
During a Metonic eclipse period, rotation observations
enable solving period proportions as follows:
235 moons = 6,958.6877 rotations
254 lunar orbits = 6,958.7014 rotations
235 : 6,958.6877 = 235.00046 : 6,958.7014
254 lunar orbits = 235.00046 moons
Subtraction solves solar orbits
254.0 - 235.00046 = 18.99954 solar orbits
Division solves rotations per orbit
254 lunar orbits = 6958.70257 rotations
6958.70257 / 18.9995407 = 366.25636 rotations per orbit
