The intent of this article is to introduce the phenomena of the De Magnis Coniunctionibus or Great Conjunctions and provide a general overview. A later article will approach the subject in more depth
The Great Conjunctions are those of Jupiter and Saturn. The last Great Conjunction occurred in May 31, 2000,. The next will be in late December 2020. They take place approximately every twenty years. Consideration of the alignment of the two social planets is most widely used in Mundane astrology.
In fact they define what we have come to call generations or epochs. I have generated the Saturn Jupiter conjunctions from 5000 B.C. to 2500 AD in pdf format.
They have been used since earliest times. Combined with other phenomena such as Solar and Lunar Eclipses. Perhaps most important is their relationship to each other
.During the twenty year period between Superior Conjunctions, they will of course square, oppose, trine or sextile one another. This is were things become a great deal more complex and will be addressed in a second article on this subject.
`The great eighth-century Persian astrologer, Masha’allah Atharī (c.740–815 AD) became the leading astrologer of his age. Here’s what he has to say about the great conjunctions and their importance in Mundane divination.
“The principal things happen from the greater kind of conjunction, which is of the superior planets. But these superior planets have other conjunctions, even ones signifying great accidents. For the conjunction and it signifies accidents and sects.
But the knowledge of the accidents from this is had by looking at the Ascendant, and the planets at the hour of their conjunction, and which of them rules the figure. Which if it were a benefic, it will signify good and the fitness of the weather. And if it were a malefic [it will signify] detriment and dryness, and moreover the sterility of the earth, and wars.” (Works of Sahl and Masha’alla “- Trans Dyke. p. 306 )
One of the best ways to get comfortable with interpreting the Great Conjunctions is to study the tables, noting the elements. Invariably, the successive Conjunctions will remain in a given element for a long periods. You can see what happened and when it happened – seeing patterns that follow this phenomena.

I look forward to more articles. This was one of the most basic and fundamental criteria for mundane astrology and astrologers. although it seems many astrologers have forgotten to look at the charts for these conjunctions. Thanks Peter.
Very useful article! Thank You!
Sharon, thank you so much for your ongoing encouragement and support . It hasn’t gone unnoticed. I’m working on an article on the English Civil War. I’ll be referring to Superior Conjunctions and a Lunar Eclipse
