Ottoman Court Astrology

An interview with Professor A. Tunç Şen about his new book, Forgotten Experts: Astrologers, Science, and Authority in the Ottoman Empire, 1450-1600, which is on astrologers working in the Ottoman court in the 15th and 16th centuries.

The conversation offers a detailed picture of the lives and social dynamics of astrologers who operated at the highest levels of power in the Ottoman court. A significant focus is the establishment of a formal unit for court astrologers, or munajjim, within the Ottoman bureaucracy, which paralleled other expert fields like physicians and architects. This unit, which could consist of one to six astrologers, was created in the 15th century and remarkably lasted until the dissolution of the Ottoman Empire in the early 20th century. 

The episode delves into the various duties performed by these court astrologers. A primary function was the practice of electional astrology, where they would determine auspicious moments for a wide range of state affairs, including military campaigns, the founding of mosques, and wedding ceremonies. The astrologers would also issue an annual almanac, interpret the birth charts of rulers, answer horary astrology questions, and sometimes give medical advice.

The conversation also explores the personalities and internal dynamics within the court. Much attention is given to Sultan Bayezid II, a ruler with a deep personal interest in the astral sciences who was instrumental in the institutionalization of the court astrologers. The story of the astrologer Riyazi is also highlighted—a highly skilled but frustrated practitioner who was never appointed chief astrologer and expressed his professional frustrations in poetry. This illustrates the debates, disagreements, and competition for authority that existed among the astrologers themselves, as well as other practitioners of esoteric or occult sciences.

The discussion challenges the narrative that astrology was in a state of decline after an earlier "golden age," demonstrating that it remained a vibrant and impactful field.
