But medieval astrologers could also quote the Bible, saying \u201cThe heavens proclaim the glory of God\u201d\u2014Psalm 19:1) and saw the heavens as part of God\u2019s Book of Nature, in which God had written signs of things to come. Astrology, medieval theologians and astrologers taught, was a science that God had revealed to the patriarchs.<\/p>\n<h3><strong>Then how did theologians get around that conundrum?<\/strong><\/h3>\n<p>That\u2019s why predictions about general matters and about large crowds seemed safer.\u00a0Theologians like Thomas Aquinas acknowledged that the stars can influence the body but not the soul, and that most human beings are swept along by their bodily passions.\u00a0Hence, astrological predictions about large-scale events, such as wars, famines, changes in rulership, even large-scale religious changes were acceptable to medieval Christians.<\/p>\n<h3><strong>In the late Middle Ages, even highly placed churchmen used these planetary conjunctions to predict the future of the Church. How so?<\/strong><\/h3>\n<p>Pierre d\u2019Ailly (1350-1420), a French cardinal who lived at the time of the Great Western Schism, when there were first two and then even three rival popes, worried like many contemporaries that the division in the church might signal the advent of Antichrist.\u00a0But he also hoped that a church council could solve the Schism.\u00a0In order to reassure himself\u2014and his contemporaries\u2014he turned to astrology and to the doctrine of the great conjunctions.\u00a0To that end, D\u2019Ailly plotted great conjunctions throughout history, noting that they presaged important religious and political changes.\u00a0For example, he pointed to a conjunction that predicted the birth of Christ and one that foretold the rise of Islam.\u00a0And he was convinced that a Saturn-Jupiter conjunction, along with other key astrological phenomena, would precede the arrival of the Antichrist\u2014which he predicted for the year 1789.<\/p>\n<h3><strong>Sometimes historic events were even \u201cfudged\u201d to make these predictions come true?<\/strong><\/h3>\n<p>Saturn-Jupiter conjunctions became an absolute mainstay of astrological predictions in the later Middle Ages and Renaissance, in part because it took very little astronomical expertise to add groups of 20 years to a known \u201croot\u201d conjunction.\u00a0One of the more famous of such conjunctions is that which occurred in 1484. After the fact it was said to have predicted the career of Martin Luther, a seminal figure in the Reformation, whose birth date was adjusted to conform to the conjunction year.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Another example is the conjunction said to have predicted Noah\u2019s Ark and the Flood. Although Pierre d\u2019Ailly had originally posited that a greatest conjunction of Saturn and Jupiter had preceded the Flood by two years, he later had to acknowledge that most astrologers placed that conjunction at an awkward 279 years beforehand. On the bright side, however, his updated chronology allowed him to locate another greatest conjunction just five years and 320 days before the Nativity and Christ\u2019s supposed birth.<\/p>\n<p>Or, astrologers could always rely upon this handy piece of astrological doctrine: the less frequent the conjunction, the slower its effects would appear. That meant, in essence, that the effects of a \u201cgreatest conjunction\u201d had 960 years in which to unfold, so that, in d\u2019Ailly\u2019s estimation, a conjunction in 36 BCE signified the birth of Muhammad, more than five centuries later. All it took was a bit of historic leeway and date fudging.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In medieval and Renaissance Europe and in the Arab world, it was widely believed that &#8220;when Saturn and Jupiter are found in the same area of the zodiac\u2014in other words when they are in conjunction\u2014there are profound effects on Earth,&#8221;
