The French historian Auguste Bouché-Leclercq (1842–1923) made major contributions to our knowledge of the Hellenistic period. A member of the Académie des Inscriptions et Belles-Lettres, he was also made an officer of the Légion d'Honneur. Bouché-Leclercq is also considered the first modern historian of astrology: he had developed a long-lasting interest in divination during his extensive researches on ancient Greek civilisation. This field had not been considered worthy of serious scholarly study until he published his Histoire de la divination dans l'antiquité between 1879 and 1882. L'Astrologie grecque, first published in 1899, is another important work, still referred to today. Bouché-Leclercq looks back to the oriental roots of Greek astrology. He delves into the specific influence of the zodiac signs, and explains how the celestial sphere was divided in order to draw horoscopes. Other topics include astrology in Roman culture, as well as astrological medicine.
