Dorotheus of Sidon


Dorotheus of Sidon was a 1st-century Greek astrologer and astrological poet, who, during the Hellenistic Period, wrote a didactic poem on horoscopic astrology in Greek, known as the Pentateuch, surviving in Greek fragments and an Arabic translation by Omar Tiberiades.
Very little is known about Dorotheus himself. Dorotheus most likely lived and worked in Alexandria, in Egypt, which, in addition to being the most important scholastic center in the Hellenistic world, was also the main location where the oldest Mesopotamian, Greek and Egyptian astrological techniques were synthesized together in order to create horoscopic astrology. According to Firmicus Maternus, Dorotheus was originally a native of the city of Sidon.

''Pentateuch''

The Pentateuch has come down to us mainly from an Arabic translation dating from around 800 AD carried out by Omar Tiberiades. The Arabic text, however, does contain interpolations by later Persian hands, but, nevertheless, remains one of our best sources for the practice of astrology during Hellenistic and Roman times, and it was a work of great influence on later Christian, Persian, Arab and medieval astrologers.
