Western astrology is the system of
astrology most popular in Western countries. Western astrology originated in
Mesopotamia during the
2nd millennium BC, from where it spread to much of the world. After spreading to
Egypt, where further developments occurred, it then arrived into Greek or
Hellenistic culture, where the Greek astronomer and astrologer
Ptolemy in his work Tetrabiblos laid the foundations of the Western tradition. Western astrology is largely
horoscopic, that is, it is largely based on the construction of a
horoscope for an exact moment in time, such as a person's birth, in which various cosmic bodies are said to have an influence. In modern Western
sun sign astrology, only the location of the
Sun is considered.
