During the Enlightenment, intellectual sympathy for astrology fell away, leaving only a popular following supported by cheap almanacs. One English almanac compiler, Richard Saunders, followed the spirit of the age by printing a derisive Discourse on the Invalidity of Astrology, while in France Pierre Bayle's Dictionnaire of 1697 stated that the subject was puerile. The Anglo-Irish satirist Jonathan Swift ridiculed the Whig political astrologer John Partridge. In the second half of the 17th century, the Society of Astrologers (1647–1684), a trade, educational, and social organization, sought to unite London's often fractious astrologers in the task of revitalizing astrology. Following the template of the popular "Feasts of Mathematicians" they endeavored to defend their art in the face of growing religious criticism. The Society hosted banquets, exchanged "instruments and manuscripts", proposed research projects, and funded the publication of sermons that depicted astrology as a legitimate biblical pursuit for Christians. They commissioned sermons that argued Astrology was divine, Hebraic, and scripturally supported by Bible passages about the Magi and the sons of Seth. According to historian Michelle Pfeffer, "The society's public relations campaign ultimately failed." Modern historians have mostly neglected the Society of Astrologers in favor of the still extant Royal Society (1660), even though both organizations initially had some of the same members. Astrology saw a popular revival starting in the 19th century, as part of a general revival of spiritualism and—later, New Age philosophy, and through the influence of mass media such as newspaper horoscopes. Early in the 20th century the psychiatrist Carl Jung developed some concepts concerning astrology, which led to the development of psychological astrology.
== Principles and practice == Advocates have defined astrology as a symbolic language, an art form, a science, and a method of divination. Though most cultural astrology systems share common roots in ancient philosophies that influenced each other, many use methods that differ from those in the West. These include Hindu astrology (also known as "Indian astrology" and in modern times referred to as "Vedic astrology") and Chinese astrology, both of which have influenced the world's cultural history.
=== Western === Western astrology is a form of divination based on the construction of a horoscope for an exact moment, such as a person's birth. It uses the tropical zodiac, which is aligned to the equinoctial points. Western astrology is founded on the movements and relative positions of celestial bodies such as the Sun, Moon and planets, which are analysed by their movement through signs of the zodiac (twelve spatial divisions of the ecliptic) and by their aspects (based on geometric angles) relative to one another. They are also considered by their placement in houses (twelve spatial divisions of the sky). Astrology's modern representation in western popular media is usually reduced to Sun sign astrology, which considers only the zodiac sign of the Sun at an individual's date of birth, and represents only 1/12 of the total chart. The horoscope visually expresses the set of relationships for the time and place of the chosen event. These relationships are between the seven 'planets', signifying tendencies such as war and love; the twelve signs of the zodiac; and the twelve houses. Each planet is in a particular sign and a particular house at the chosen time, when observed from the chosen place, creating two kinds of relationship. A third kind is the aspect of each planet to every other planet, where for example two planets 120° apart (in 'trine') are in a harmonious relationship, but two planets 90° apart ('square') are in a conflicted relationship. Together these relationships and their interpretations are said to form "...the language of the heavens speaking to learned men." Along with tarot divination, astrology is one of the core studies of Western esotericism, and as such has influenced systems of magical belief not only among Western esotericists and Hermeticists, but also belief systems such as Wicca, which have borrowed from or been influenced by the Western esoteric tradition. Tanya Luhrmann has said that "all magicians know something about astrology," and refers to a table of correspondences in Starhawk's The Spiral Dance, organised by planet, as an example of the astrological lore studied by magicians.
=== Hindu ===
The earliest Vedic text on astronomy is the Vedanga Jyotisha; Vedic thought later came to include astrology as well. Hindu natal astrology originated with Hellenistic astrology by the 3rd century BCE, though incorporating the Hindu lunar mansions. The names of the signs (e.g. Greek 'Krios' for Aries, Hindi 'Kriya'), the planets (e.g. Greek 'Helios' for Sun, astrological Hindi 'Heli'), and astrological terms (e.g. Greek 'apoklima' and 'sunaphe' for declination and planetary conjunction, Hindi 'apoklima' and 'sunapha' respectively) in Varaha Mihira's texts are considered conclusive evidence of a Greek origin for Hindu astrology. The Indian techniques may also have been augmented with some of the Babylonian techniques.
