Propositions of Astronomical Circles


Proposition I: The respective and relative motion of three gravitating bodies revolving together and about each other, is as four to three, or one and one-third of one primary circumference. First Proportion: As one primary circumference of a circle is to the moon's time about the earth, so is the moon's time about the earth to the earth's time about the sun." An excellent paper detailing the relationships of planetary properties (orbits, sizes, etc.) relative to the Quadrature of the Circle. Some attribute this marvelous and singular work to John Parker, mathematician. 8.5" X 11"
