Eight hundred years, or the revolution through four trigons Groups of three zodiac signs belonging to the same element. of these conjunctions Meetings where planets appear at the same point in the sky. and oppositions Alignments where planets are on opposite sides of the Earth., were called by the Platonists Followers of the philosophy of Plato, who often sought mathematical harmony in the cosmos. the Greatest Time original: "Tempus maximum"—
Four hundred years, or the revolution through two trigons, was called the Middle Time original: "Tempus medium"—
A quarter of the revolution, or the conjunctions and oppositions in a single trigon, was called the Least Time original: "Tempus minimum".
The observations made in meteorology by the Egyptians showed that between 18 and 19 years—namely, shortly before a conjunction or opposition of Saturn and Jupiter—almost the same weather conditions recur and the same winds appear. This prompted them even more to precisely understand the system of meetings and oppositions between Saturn and Jupiter. Because of this meteorological study, the view of these conjunctions and oppositions of Saturn and Jupiter is also worthy of our attention; I present an essay on this to my worthy readers at the end of this work.
Many years of observation had fully convinced the ancient Egyptians that Saturn, because of its slow pace, requires nearly 30 years to wander through the 12 signs of the Zodiac. Jupiter, however, requires 12 years to complete the same path; consequently, in a period of 30 years, it has already completed its circuit two and a half times The original German "dritthalbmal" is an archaic expression meaning "half of the third," or 2.5. before Saturn comes around once. In the time that Jupiter wanders through them,
