Hephaestion of Thebes
Hephaestion, Hephaistion, or Hephaistio of Thebes was a Hellenized Egyptian astrologer of late Antiquity who wrote a Greek treatise known as the Apotelesmatics or Apotelesmatika around 415. Much of the work appears to be an attempt to synthesize the earlier works of the 1st century astrologer Dorotheus of Sidon and the 2nd century astrologer Claudius Ptolemy. Hephaestion is seen mainly as one of the later compilers of the Hellenistic tradition of astrology since he mainly draws from earlier astrologers, including Antiochus of Athens, and he summarizes large portions of Ptolemy and Dorotheus, which is helpful to modern scholars since we have no other record of many of the authorities that he quotes.
Hephaestion's intention appears to have been to reconcile the authoritative Ptolemaic tradition with the earlier practices represented by Dorotheus of Sidon. He wrote at a time and in a place when astrological ideas were being summarized and consolidated, after the removal of the capital of the Empire from Rome to Constantinople. His contemporaries included Paulus Alexandrinus and the anonymous author of the well-known Treatise on Fixed Stars.
Although influential on later Byzantine astrologers, his work seems to have had little impact in the Arab tradition which followed. The first two volumes of the Apotelesmatics have been translated into English ; the third volume on Katarchic astrology is in preparation.
