The progression The shifting movement of the points where planets meet relative to the fixed stars/degrees of the zodiac. of the conjunctions Conjunction: When two planets align at the same point in the sky. in degrees is always, for every 3 degrees, a little less than 2 minutes.
After every seventh conjunction, a change in the calculation arises, so that at the seventh, instead of 20 years, only 19 must be reckoned; and because there is a lack of 26 days in the distance between each conjunction and opposition Opposition: When two planets are on opposite sides of the Earth, 180 degrees apart. when calculated at 10 years; it follows that after ninety conjunctions, a ninety-first must follow in the same Trigon Trigon: A group of three zodiac signs belonging to the same element; these planets meet within signs of the same element for approximately 200 years before moving to the next element..
Both because of the aforementioned meteorological observations and for knowledge of the sublime calculus Calculus: A systematic method of astronomical computation or the "math of the heavens." of the universe, I have placed at the end of this treatise a table of all conjunctions of Saturn and Jupiter from the beginning of the world until our own, and even somewhat later, times.
According to the expression: "great year" original: "annus magnus" — a concept where a "year" is measured by the time it takes for all planets to return to a specific alignment, here referring to the 800-year cycle of Saturn and Jupiter., which was attributed to the revolution Revolution: The completion of a full orbital cycle or periodic return to a starting point. of both planets after 800 years, it would therefore be no absurdity to say that the terrestrial globe upon which we live is currently only 7 1/4 years old The author is calculating based on a biblical age of the world (approx. 5,800 years); 5,800 divided by the 800-year "Great Year" equals roughly 7.25..
Even to modern astronomers, the sublime order of the greater conjunctions and oppositions of Saturn and Jupiter is a majestic spectacle.
