Berosus (fl. 290 B.C.E.)
Berosus is the Babylonian priest most responsible for
spreading Chaldean astrological ideas to Greece. Berosus was
born and raised in Babylon (present-day Iraq). He was a contemporary
of Alexander the Great, who died at Babylon when
Berosus was still a child. As an adult he traveled to Greece and
settled on the Island of Cos, where he founded a school of astrology.
Around 280 B.C.E. he wrote a history of his homeland;
only fragments of this document remain. His greater influence
came from the number of students he trained who went on to
teach astrology throughout Greece. The Babylonian astrologers
were the first to carefully map the night sky and to calculate
the length of the solar years (to within 26 minutes). They
greatly improved methods of forecasting eclipses and recording
