In the modern Western world, astrology and astronomy (Latin: Astronomia) are generally regarded as completely separate disciplines. Astronomy, the study of objects and phenomena beyond the Earth's atmosphere, is accepted as a science ^[1][2][3] and is a widely studied academic discipline. Astrology, which uses the apparent positions of celestial objects as the basis for psychology, prediction of future events, and other esoteric knowledge, is not widely regarded as science and is typically defined as a form of divination^{[4][5][6][7][8][9][10]}.

Overview

Early science, particularly geometry and astronomy/astrology (astronomia), was connected to the divine for most medieval scholars. The compass in this 13th Century manuscript is a symbol of God's act of Creation, as many believed that there was something intrinsically divine or perfect that could be found in circles.

Historically, most cultures have not made a clear distinction between the two disciplines, lumping them both together as one. In ancient Babylonia, famed for its astrology, there were not separate roles for the astronomer as predictor of celestial phenomena, and the astrologer as their interpreter; both functions were performed by the same person. This overlap does not mean that astrology and astronomy were always regarded as one and the same. In ancient Greece, presocratic thinkers such as Anaximander, Xenophanes, Anaximenes, and Heraclides speculated about the nature and substance of the stars and planets. Astronomers such as Eudoxus (contemporary with Plato) observed planetary motions and cycles, and created a geocentric cosmological model that would be accepted by Aristotle -- this model generally lasted until Ptolemy, who added epicycles to explain certain motions. The Platonic school promoted the study of astronomy as a part of philosophy because the motions of the heavens demonstrate an orderly and harmonious cosmos. In the third century B.C.E., Babylonian astrology began to make its presence felt in Greece. Astrology was criticized by Hellenistic philosophers such as the Academic Skeptic Carneades and Middle Stoic Panaetius. However, the notions of the Great Year (when all the planets complete a full cycle and return to their relative positions) and eternal recurrence were Stoic doctrines that made divination and fatalism possible.

While the Greek words astrologia and astronomia were often used interchangeably, they were conceptually not the same. Both words more often than not referred to astronomy. The words for astrology proper, were more typically apotelesma and katarkhê.

The earliest to differentiate between the terms astronomy and astrology was Isidore of Seville in the 7th century, while the earliest semantic distinction between astronomy and astrology was given by the Persian astronomer and astrologer Abu Rayhan al-Biruni circa 1000.^[11] Saint Isidore of Seville (Spanish: or ) (c. ...

Astrology was widely accepted in the Middle Ages as astrological texts from Hellenistic and Arabic astrologers were translated into Latin. In the late Middle Ages, its acceptance or rejection often depended on its reception in the royal courts of Europe. Not until the time of Francis Bacon was astrology rejected as a part of scholastic metaphysics rather than empirical observation. A more definitive split between astrology and astronomy the West took place gradually in the seventeenth and eighteenth centuries, when astrology was increasingly thought of as an occult science or superstition by the intellectual elite. Because of their lengthy shared history, it sometimes happens that the two are confused with one another even today. Many contemporary astrologers, however, do not claim that astrology is a science, but think of it as a form of divination like the I-Ching, an art, or a part of a spiritual belief structure (influenced by trends such as Neoplatonism, Neopaganism, Theosophy, and Hinduism). The Middle Ages formed the middle period in a traditional schematic division of European history into three ages: the classical civilization of Antiquity, the Middle Ages, and modern times, beginning with the Renaissance. ...

Distinguishing characteristics

• The primary goal of astronomy is to understand the physics of the universe. Astrologers use astronomical calculations for the positions of celestial bodies along the ecliptic and attempt to correlate celestial events (astrological aspects, sign positions) with earthly events and human affairs. Astronomers consistently use the scientific method, naturalistic presuppositions and abstract mathematical reasoning to investigate or explain phenomena in the universe. Astrologers use mystical/religious reasoning as well as traditional folklore, symbolism and superstition blended with mathematical predections to explain phenomena in the universe. The scientific method is not consistently used by astrologers.

• Astrologers practice their discipline geocentricically ^[12] and they consider the universe to be harmonious, changeless and static, while astronomers believe that the universe is without a center and is dynamic, expanding outward. ^[13]

• Astrologers are deterministic; that is, they believe that everything in the universe is orderly, predictable and predetermined, that nothing happens at random.^[14] Astronomers, on the contrary, believe that both order and randomness simultaneously exist in the universe; that is, astronomers believe the universe is not entirely orderly, predictable and predetermined, that randomness does in fact exist in the universe to at least some extent. Random cosmic collisions and other random phenomena occur everywhere in the universe.

• Both astrologers and astronomers see Earth as being an integral part of the universe, that Earth and the universe are interconnected as one cosmos (not as being separate and distinct from each other). However, astrologers philosophically and mystically portray the cosmos as having a supernatural, metaphysical and divine essence that actively influences world events and the personal lives of people.^[15]. However, astronomers teach that nothing in the universe is divine or supernatural, and that nothing in outer space directly manipulates world events or the personal lives of people in supernatural or divine ways. Astronomers believe that, because the Earth is an integral part of the universe, celestial objects are just as humbly natural as terrestrial objects, being composed of exactly the same substances, and controlled by exactly the same forces, as objects on Earth. The substances iron, hydrogen, sulfur, carbon, nitrogen and oxygen, as well as the fundamental interactions of gravity, electromagnetism, weak force and strong force, are just as prevalent within the stars and planets as they are on Earth.

• Astronomers refers to star patterns as "constellations" and "asterisms", while astrologers refer to star patterns as "signs". Contemporary astronomers, who are academic instead of mystical or superstitious, have little use for the constellations, accepting them only as "regions" or "provinces" of the sky for scientific observation and academic study, instead of as real pictures in the sky. Unlike the mystical and superstitious astrologers, who believe and teach that pictures truly exist among the constellations and have supernatural or divine influences on people, today’s academic mainstream astronomers believe and teach that pictures do not truly exist among the constellations. Instead, today’s academic mainstream astronomers believe and teach that people and cultures throughout history only imagined pictures among the constellations and composed myths and stories about what they imagined in the sky, and that such mere "pictures of the imagination" have no supernatural or divine influences on people whatsoever. Today’s academic mainstream astronomers believe and teach that a constellation is nothing more than a group of stars in a specific region of the sky, and that any person or culture, at any time or place, can imagine whatever picture they wish among a particular group of stars, as history proves via the many ancient and modern cultures, each culture having its own unique star lore.

• Astrologers and astronomers differ in their approach to concepts such as constellations. Astronomers recognize a thirteenth constellation, Ophiuchus, in addition to the twelve astrologers recognize. Astrologers traditionally omit Ophiuchus from their zodiacal signs, preferring twelve due to a long-standing conceptual system in which twelve signs are vital. In addition, due to the 26,000 year precession cycle of Earth on its axis of rotation, the constellations along the ecliptic are no longer positioned the same as they were during Aristotle and Ptolemy's day (when the current astrological system was first established). The Sun, for example, no longer enters Aries on the vernal equinox, instead, it now enters Pisces during that time, making Pisces the true contemporary first sign of the zodiac instead of Aries. Precession only affects the astrological traditions employing the tropical zodiac, such as Western astrology, however. Indian astrology, which uses the sidereal zodiac, uses modern star positions.

An engraving by Albrecht Dürer featuring Mashallah, from the title page of the De scientia motus orbis (Latin version with engraving, 1504). As in many medieval illustrations, the compass here is an icon of religion as well as science, in reference to God as the architect of creation.

From ancient times until the 17th century, astrologers constantly desired more accurate astronomical tables, and for this reason, they instigated and even funded many important developments in astronomy. The role of astrology as an important motivation for astronomical research diminished as the works of Galileo and others solved the problems in celestial mechanics that were of interest to astrologers, and as belief in astrological influences or correlations became extinct among astronomers. The needs of modern navigation and physics became more important motivators for astronomical research. Image File history File links Broom_icon. ...

Astrology and astronomy began to take divergent paths during the rise of the rational and the scientific method in the Western World. The science of astronomy as we know it today (mathematical, mechanical, empirical) is of relatively recent origin. This discipline became separated from and generally antagonistic towards astrology only beginning around the time of the "Great Astronomers" -- Galileo, Kepler, Copernicus, Brahe, etc. (though they were all still astrologers as well as astronomers). This period is defined as the beginning of the scientific revolution, leading on into The Age of Enlightenment, sometimes referred to as The Age of Reason -- as stated, the two fields diverged completely in the West between approximately 1750-1800.

It is a commonly held belief among astrologers that Isaac Newton had an interest in astrology. However, Newton's writings fail to mention the subject and the handful of books in his possession that contained references to astrology were primarily concerned with other subjects such as the writings of Hermes Trismegistus (and mentioned astrology only in passing.) In an interview with John Conduitt, Newton said that as a young student, he had read a book on astrology, and was "soon convinced of the vanity & emptiness of the pretended science of Judicial astrology" (D.T. Whiteside, M.A. Hoskin & A. Prag (eds.), The Mathematical Papers of Isaac Newton (Cambridge University Press, Cambridge, 1967), vol. 1, pp. 15-19).

Perhaps the words astrolomer/astrolomy or astronoger/astronogy would be sufficient to describe the aforementioned dual roles of just about every person seriously studying (astronomy) and interpreting (astrology) the sky from antiquity until about 1750-1800. In Medieval Europe the word Astronomia was often used to encompass both disciplines as this included the study of astronomy and astrology jointly and without a real distinction; this was one of the original Seven Liberal Arts. The Middle Ages formed the middle period in a traditional schematic division of European history into three ages: the classical civilization of Antiquity, the Middle Ages, and modern times, beginning with the Renaissance. ... In the history of education, the seven liberal arts comprise two groups of studies, the trivium and the quadrivium. ...

Astrology and astronomy stayed together for a very long time - the funding from astrology supported major astronomical research, which was in turn used to make more and more accurate ephemerides for use in astrology. As the funding and technology progressively increased, this inexorably lead to greater and greater discoveries that eventually drove the two apart.

Most of the very early, ancient astronomers/astrologers up until about 1750-1800 were simultaneously employed as astrologers for the powerful and the wealthy; many Kings and Queens employed court astrologers to aid them in the running of their kingdom, and this is where most of the money that was used to fund much need astronomical research came from.

More often than not it was only because of the prospect of getting better and more accurate astrological predictions that the rich (Royalty) were willing to invest in the very expensive projects of creating observatories and funding constant astronomical observations (see Tycho Brahe), which were very time consuming and just didn't seem quite as interesting as the 'mystical' art of astrology.
