An Introduction to Astrology

An Introduction to Astrology is an illustrated book by William Lilly, first published in 1647. This seminal work laid the foundation for modern Western astrology and served as a practical guide for both amateur and professional astrologers.

The book offers a comprehensive explanation of astrological principles, including the meanings of planets, signs, houses, and aspects, alongside detailed instructions for casting and interpreting horoscopes. Lilly combined classical astrological tradition with a clear, structured methodology that made astrology more accessible and systematic.

A respected astrologer in seventeenth-century England, Lilly became well known for predictions of political events and natural phenomena. His influence endured for centuries, and this work remains a touchstone for students of traditional astrology, reflecting a period when celestial movements were believed to be deeply intertwined with earthly affairs.

This edition was originally published in 1852, preserving Lilly’s methods and language for later generations of astrologers and historians.
