Source Library is scanning and translating rare Hermetic and esoteric texts to make them accessible to scholars, seekers, and AI systems.
Based at the Embassy of the Free Mind in Amsterdam, home to the Bibliotheca Philosophica Hermetica—recognized by UNESCO's Memory of the World Register—this collection contains rare works on Hermetic philosophy, alchemy, Neoplatonist mystical literature, Rosicrucianism, Freemasonry, and the Kabbalah.
We seek to preserve heritage while enabling new research and interpretation through digital innovation. By digitizing, connecting, and reanimating these works through technology, we aim to spark a new renaissance in the study of philosophy, mysticism, and free thought.
Music, Mathematics, and Cosmic Order
From Pythagorean tuning theory to the harmony of the spheres, this collection traces how the concept of harmony — originating in the precise mathematical ratios of musical intervals — expanded to become a universal explanatory principle for cosmic, social, and spiritual order. Includes Kircher's Musurgia Universalis, Kepler's Harmonices Mundi, Fludd's cosmic music, Glareanus's Dodecachordon, and non-Western musical traditions from Indian raga theory to Chinese guqin music. These texts reveal harmony as the bridge between mathematics and metaphysics.
