📝 Description: Christian Astrology: Book One

Originally published in 1647, this Cosimo Classics hardcover edition presents William Lilly's classic manual on horary astrology. Lilly was a prominent English astrologer of the 17th century who famously predicted the Great Fire of London of 1666 fourteen years beforehand. During the English Civil War, he used his expertise as a trusted advisor to various politicians and soldiers while supporting the anti-royal Roundhead factions. His background makes him a uniquely qualified guide to casting horary horoscopes, which construct astrological charts to answer specific questions. Book One of this work details the characteristics and motions of the seven planets. It opens with an examination of planetary natures, including explicit entries such as Of the Planet Venus and her feverall fignifications and nature. Beyond planetary traits, the text teaches readers how to cast horary charts and how to determine whether predicted events will actually come to pass. The volume presents a foundational methodology for reading charts and evaluating outcomes based on historical English astrological practices. This volume suits contemporary fans of astrology and readers interested in the history of the paranormal who want a direct historical source on horary methods. It does not suit those looking for modern psychological astrology or a broad overview of non-Western traditions, as it focuses strictly on traditional 17th-century European methods. Readers seeking additional material can also consult Book Two and Book Three, which are published separately.

Esoterica Books editorial team
Occult literature desk
Lilly’s monumental 1647 treatise remains a cornerstone for those dedicated to the rigorous study of English horary astrology. It offers a systematic approach to deciphering planetary omens with authoritative precision, making it invaluable for serious diviners. However, this text is not suitable for casual readers seeking light entertainment or modern psychological interpretations. Its dense, demanding nature and unvarnished depiction of malefic influences may alienate those preferring gentle or abstract astrological theories. It requires patience and a willingness to engage with early modern empirical observation rather than contemporary trends. Only those committed to the historical and technical depths of Renaissance magic will find it rewarding.

Solid edition

Grabbed this during a weekend order. I appreciated how the argument builds steadily from first principles. The font runs small in the appendices. Happy enough with the purchase.

Good but demanding

Grabbed this during a weekend order. It pairs well with more modern commentaries on the same tradition. Challenging in places, but never needlessly obscure. My only quibble is the cover feels thinner than expected. Still worth having on the shelf.

Bought this as a gift for my sister and ended up ordering a second copy for myself. Not a light read, but far more accessible than I feared. My only quibble is the cover feels thinner than expected.

Exceeded expectations

Not my usual area but wanted to branch out. It connects ideas I'd only seen treated separately elsewhere. Every rereading turns up something I missed. Already eyeing my next order.

❓ Frequently asked questions

Not ideally. While it is a foundational text, its dense 17th-century prose and complex technical instructions may overwhelm those new to astrology without prior study or a guide.
Primarily, it focuses on horary astrology—answering specific questions at the moment they are asked—rather than life-path natal readings, though the planetary principles apply to both.

📖 Who should read this

Seekers of historical esotericism, practicing astrologers interested in the roots of horary techniques, and historians of science. It suits those willing to engage with dense, archaic prose to understand the foundational logic of predictive astrology.

📜 Historical context

Published during the English Civil War, Lilly’s work emerged when astrology was still a respected scholarly pursuit rather than mere entertainment. As the most prominent English astrologer of his era, Lilly advised Parliamentarians and predicted major historical events. This text codified the practice of answering specific queries via natal charts, influencing subsequent generations of occultists and establishing a standard for divinatory rigor that persists in modern hermetic circles.
