Astrological signIn Western astrology, astrological signs are the twelve 30-degree sectors that make up Earth's 360-degree orbit around the Sun. The signs enumerate from the first day of spring, known as the First Point of Aries, which is the vernal equinox. The astrological signs are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The Western zodiac originated in Babylonian astrology, and was later influenced by the Hellenistic culture.
Western astrologyWestern astrology is the system of astrology most popular in Western countries. Western astrology is historically based on Ptolemy's Tetrabiblos (2nd century CE), which in turn was a continuation of Hellenistic and ultimately Babylonian traditions. Western astrology is largely horoscopic, that is, it is a form of divination based on the construction of a horoscope for an exact moment, such as a person's birth as well as location (since time zones may or may not affect a person's birth chart), in which various cosmic bodies are said to have an influence.
AstrologyAstrology is a range of divinatory practices, recognized as pseudoscientific since the 18th century, that claim to discern information about human affairs and terrestrial events by studying the apparent positions of celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications.
Hindu astrologyHindu astrology, also called Indian astrology, Jyotisha or Jyotishya (from Sanskrit , from “light, heavenly body"), and more recently Vedic astrology, is the traditional Hindu system of astrology. It is one of the six auxiliary disciplines in Hinduism that is connected with the study of the Vedas. The Vedanga Jyotisha is one of the earliest texts about astronomy within the Vedas. Some scholars believe that the horoscopic astrology practiced in the Indian subcontinent came from Hellenistic influences.
Horoscopic astrologyHoroscopic astrology is a form of astrology that uses a horoscope, a visual representation of the heavens, for a specific moment in time to interpret the purported meaning behind the alignment of the planets at that moment. The idea is that the placement of the planets at any given moment in time supposedly reflects the nature of that moment and especially anything that is born then, and proponents claim that this can be analyzed using the chart and a variety of rules for interpreting the "language" or symbols therein.
TetrabiblosTetrabiblos (Τετράβιβλος) 'four books', also known in Greek as Apotelesmatiká (Ἀποτελεσματικά) "Effects", and in Latin as Quadripartitum "Four Parts", is a text on the philosophy and practice of astrology, written in the 2nd century AD by the Alexandrian scholar Claudius Ptolemy ( AD 90– AD 168). Ptolemy's Almagest was an authoritative text on astronomy for more than a thousand years, and the Tetrabiblos, its companion volume, was equally influential in astrology, the study of the effects of astronomical cycles on earthly matters.
Hellenistic astrologyHellenistic astrology is a tradition of horoscopic astrology that was developed and practiced in the late Hellenistic period in and around the Mediterranean Basin region, especially in Egypt. The texts and technical terminology of this tradition of astrology were largely written in Greek (or sometimes Latin). The tradition originated sometime around the late 2nd or early 1st century BCE, and then was practiced until the 6th or 7th century CE.
Planets in astrologyIn astrology, planets have a meaning different from the astronomical understanding of what a planet is. Before the age of telescopes, the night sky was thought to consist of two similar components: fixed stars, which remained motionless in relation to each other, and moving objects/"wandering stars" (asteres planetai), which moved relative to the fixed stars over the course of the year(s). To the Ancient Greeks who learned from the Babylonians - the earliest astronomers/astrologers - this group consisted of the five planets visible to the naked eye and excluded Earth, plus the Sun and Moon.
Chinese zodiacThe Chinese zodiac is a traditional classification scheme based on the Chinese calendar that assigns an animal and its reputed attributes to each year in a repeating twelve-year cycle. Originating from China, the zodiac and its variations remain popular in many East Asian and Southeast Asian countries, such as Japan, South Korea, Vietnam, Singapore, Nepal, Bhutan, Cambodia, and Thailand.
Astrology and scienceAstrology consists of a number of belief systems that hold that there is a relationship between astronomical phenomena and events or descriptions of personality in the human world. Astrology has been rejected by the scientific community as having no explanatory power for describing the universe. Scientific testing has found no evidence to support the premises or purported effects outlined in astrological traditions. Where astrology has made falsifiable predictions, it has been falsified.
