Astrology 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. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from where it spread to Ancient Greece, Rome, the Islamic world, and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems.

In 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. Each sign was named after a constellation the sun annually moved through while crossing the sky. This observation is emphasized in the simplified and popular sun sign astrology. Over the centuries, Western astrology's zodiacal divisions have shifted out of alignment with the constellations they were named after by axial precession of the Earth while Hindu astrology measurements correct for this shifting. Astrology was developed in Chinese and Tibetan cultures as well but these astrologies are not based upon the zodiac but deal with the whole sky.
The Testament of Solomon is a pseudepigraphical composite text ascribed to King Solomon but not regarded as canonical scripture by Jews or Christian groups. It was written in the Greek language, based on precedents dating back to the early 1st millennium CE, but was likely not completed in any meaningful textual sense until sometime in the Middle Ages. In its most noteworthy recensions, the text describes how Solomon was enabled to build his temple by commanding demons by means of a magical ring that was entrusted to him by the archangel Michael.
Astrological belief in correspondences between celestial observations and terrestrial events have influenced various aspects of human history, including world-views, language and many elements of social culture.
In astrology, exaltation is one of the five essential dignities of a planet. The exaltation is a place of awareness for the planet, whereas the fall is a position of weakness concerning the function of the planet. The sign position directly opposite a planet's sign of exaltation is considered to be its fall.
Essential dignity, in the context of an astrological horoscope or natal chart, refers to the relative “strength” or “weakness” of a planet based on its zodiac sign and specific degree. This strength or weakness is referred to as the planet’s essence—what the 17th-century astrologer William Lilly called "the strength, fortitude or debility of the Planets [or] significators."
In astrology, the line of advantage is an imaginary line that connects the third decan of the third house to the third decan of the ninth house of the horoscope. If the North Node of the Moon falls east of the line of advantage, it is believed to be a favourable and advantageous position within the horoscope.
In astrology, a decan is the subdivision of a sign. In order to give fuller interpretation to the zodiac signs, ancient astrologers subdivided each sign into periods of approximately ten days. These divisions are known as the "decans" or "decantes" and cover modifications of individual traits, attributed to minor planetary influences, which temper or blend with the ruling influence of the period. The ten-day spans are somewhat arbitrary in order to allow for the five extra days in the year beyond the 360 days required for the thirty-six decans.
In astrology, a dwadasamsa, which is also called a dwad, duad or dwadachamsha, is 1/12 of a zodiacal sign. The dwadasamsa was developed by Hindu astrologers who broke the 30 degree sign down into 12 equal parts of 2.5 degrees each. It is based upon the principle of the part being a reflection of the whole, and 12 signs of the zodiac were placed within the confines of one sign. It is believed that these signs within a sign, by virtue of their planetary rulers, account for subtle shadings of expression found in different degrees of that sign. Therefore, in addition to the sign having a primary planetary ruler, it would also have a sub-ruler, based upon which dwadasamsa it is placed in.
The decans are 36 groups of stars used in the ancient Egyptian astronomy to conveniently divide the 360 degree ecliptic into 36 parts of 10 degrees each, both for theurgical and heliacal horological purposes. The decans each appeared, geocentrically, to rise consecutively on the horizon throughout each daily earth rotation. The rising of each decan marked the beginning of a new decanal "hour" of the night for the ancient Egyptians, and they were used as a sidereal star clock beginning by at least the 9th or 10th Dynasty.
Often called lunar mansion, a lunar station or lunar house is a segment of the ecliptic through which the Moon passes in its orbit around the Earth. The concept was used by several ancient cultures as part of their calendrical system.
Hellenistic 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. The tradition originated sometime around the late 2nd or early 1st century BCE, and then was practiced until the 6th or 7th century CE. This type of astrology is commonly referred to as "Hellenistic astrology" because it was developed in the late Hellenistic period, although it continued to be practiced for several centuries after the end of what historians usually classify as the Hellenistic era.

Teucer of Babylon was an ancient Egyptian astrologer of uncertain date, though likely in or before the first century AD. David Pingree concluded that he is used as a source by Vettius Valens and Rhetorius, which dates him to at least the first century AD, while Wolfgang Hübner argues Marcus Manilius and Julius Firmicus Maternus drew on some of his materials, dating him to at least the first century BC. Teucer is mentioned by the philosopher Porphyry, which places him definitively before the third century AD.
