Astrology
Astrology. The reading of celestial events as signs bearing on human affairs. The anchor is the Babylonian celestial omen literature from about 1800 BCE — observations recorded because they were held to portend, with the great compilation Enuma Anu Enlil assembled much later. Astrology and astronomy are one practice at this date and separate only slowly. The omen tradition is the reason the observations were kept at all, which means the systematic record astronomy later built on exists because somebody wanted to know what it meant. The subject remains live: astrology never ended, it only stopped being science.
