Astrological Prophecies of the Great Conjunctions

Record summary

Medieval and early modern European astrologers used Jupiter–Saturn conjunctions, especially the so-called great conjunctions, to organize long-term forecasts about dynastic change, religion, plague, war, and world ages. The tradition drew on Arabic, Persian, and Latin astrological authorities and was repeatedly recalculated as astronomical tables improved. It matters for comparison because it shows a durable forecasting framework rather than one isolated prediction. Interpretive systems, planetary calculations, and the meaning of conjunction cycles varied significantly across authors and periods.
