Astrologers at Work: Essays on the Practices and Techniques of Astrology in Memory of Helena Avelar

Astrologers at Work brings together fourteen scholars to explore the history of astrological practice, focusing on techniques, doctrines, and methods of interpretation across cultures and centuries. Originating from the Tools of the Art conference, organised by the Astra Project in memory of Helena Avelar, this volume highlights astrology’s technical and intellectual dimensions, placing it at the heart of pre-modern science and culture. Through detailed studies of charts, doctrines, and practices, it reveals the central role astrology played in shaping ideas about nature, knowledge, and fate. This work is a vital contribution to the history of science, culture, and ideas.
