For many people, modern astrology means one thing: the horoscope. But the horoscope did not begin as a push notification about your sun sign.

“Instead of interpreting an entire chart, he could sort every reader into one of twelve categories based on their sun sign.”

In its original sense, a horoscope was an astrological chart. For centuries, astrologers have mapped the sky for specific moments, calculating the positions of the planets and interpreting what they might mean. That history stretches far beyond modern media and far beyond Britain.
