History of astrology

An astrolabe (Greek: ἀστρολάβος astrolabos, "star-taker") is an elaborate inclinometer, historically used by astronomers, navigators, and astrologers.

The Planets, Op. 32, is a seven-movement orchestral suite by the English composer Gustav Holst, written between 1914 and 1916.

Musica universalis (literally universal music), also called Music of the spheres or Harmony of the Spheres, is an ancient philosophical concept that regards proportions in the movements of celestial bodies—the Sun, Moon, and planets—as a form of musica (the Medieval Latin term for music).

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World (see astrology and astronomy).

The zodiac is the circle of twelve 30° divisions of celestial longitude employed by western astrology and (formerly) astronomy.

An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (in the celestial sphere), consisting of a spherical framework of rings, centred on Earth or the Sun, that represent lines of celestial longitude and latitude and other astronomically important features such as the ecliptic.

Geomancy (Greek: γεωμαντεία, "earth divination") is a method of divination that interprets markings on the ground or the patterns formed by tossed handfuls of soil, rocks, or sand.

International Astrology Day (most often observed on either March 20 or March 21) is an annual observance/holiday celebrated by astrologers and astrology enthusiasts.

An astronomical clock is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the sun, moon, zodiacal constellations, and sometimes major planets.

An omen (also called portent or presage) is a phenomenon that is believed to foretell the future, often signifying the advent of change.

Hebrew astronomy refers to any astronomy written in Hebrew or by Hebrew speakers, or translated into Hebrew.

Historically, the term 'Kosmobiologie' was used by the German medical astrologer Friedrich Feerhow and Swiss statistician Karl Krafft in a more general sense "to designate that branch of astrology working on scientific foundations and keyed to the natural sciences".

The cosmolabe was an ancient astronomical instrument resembling the astrolabe, formerly used for measuring the angles between heavenly bodies.

In Babylon as well as in Assyria as a direct offshoot of Babylonian culture, astrology takes its place as one of the two chief means at the disposal of the priests (who were called bare or "inspectors") for ascertaining the will and intention of the gods, the other being through the inspection of the livers of sacrificial animals (see omen).
