Byzantine astrology is rather unknown among the general public. In fact, many people might be surprised to find out that Byzantine astrology even existed. It did, though, and it was marvelous!
Byzantium was somehow a continuation of the Hellenistic world, so
astrology was a natural part of its tradition. Additionally, the Byzantines
were geographically close to the Persians and Arabs - who themselves had
adopted and developed the Hellenistic astrology. Consequently,
Byzantium became a particularly fertile ground for the dissemination of
astrological ideas, at the time.
