“An Astrolo-Physical Compendium, or a Brief Introduction to Astrology” by Richard Ball, published in 1697, is a seminal work that interlaces the disciplines of astrology and herbal medicine. This compendium serves as a guide for readers to understand how celestial movements influence both human health and the natural world, particularly the properties and applications of English herbs. Ball, an astro-mathematicus, provides a structured approach to interpreting the heavens and applying this knowledge to practical healing methods.​

The book begins by introducing the fundamentals of astrology, detailing the significance of celestial bodies and their movements. Ball explains how the positions of stars and planets can be used to make informed judgments on various matters, including health-related issues. He emphasizes that individuals, even those without extensive prior knowledge, can learn to interpret these cosmic signs to address specific questions or concerns. This approach reflects the 17th-century belief in the interconnectedness of the cosmos and human affairs, where understanding the heavens was seen as a pathway to understanding earthly events.​

A significant portion of the compendium is dedicated to the relationship between planets and English herbs. Ball outlines which planets govern specific herbs and provides guidance on the optimal times for harvesting them, based on astrological considerations. He further discusses how to apply these herbs in treating various ailments, aligning the treatment with the nature of the illness and the affected body part. This section underscores the holistic approach of the time, where medicine was not only about the physical properties of herbs but also about their celestial associations.​

Ball’s work is a reflection of the era’s attempt to harmonize scientific observation with spiritual and astrological beliefs. By combining detailed astrological instruction with practical herbal applications, “An Astrolo-Physical Compendium” offers a comprehensive guide for those seeking to understand and utilize the perceived connections between the cosmos and natural remedies. It stands as a testament to the historical efforts to integrate various fields of knowledge in the pursuit of health and understanding.
