The Lost Keys of Masonry

The Lost Keys of Masonry: The Legend of Hiram Abiff is a book by Canadian mystic and Freemason Manly P. Hall, first published in 1923. Renowned for his deep engagement with occult and esoteric ideas, Hall explores the symbolic journey undertaken by initiates within Freemasonry, presenting the tradition as a living system of moral and philosophical instruction rather than a merely historical institution.

The book examines the ethical principles at the heart of Masonic teaching, alongside the character virtues that aspirants are expected to cultivate. Through the central legend of Hiram Abiff, Hall frames Freemasonry as a continuation of ancient mystery traditions, preserving timeless lessons through ritual, symbol, and allegory.

Both interpretive and aspirational in tone, the work traces the inner progression from novice to adept, revealing why Masonic symbolism has continued to captivate successive generations. It remains a compelling introduction to Masonic thought, appealing to committed members and thoughtful outsiders alike.
