Dorotheus of Sidon (Ancient Greek: Δωρόθεος Σιδώνιος, c. 75 CE - ??
five books; more commonly known in the Western world as Carmen Astrologicum[2]).
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.
The late 1st century, a time when Dorotheus is believed to have flourished, was a period of intense astrological development, following two millennia of accumulated tradition.
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.
