Monas Hieroglyphica (or The Hieroglyphic Monad) is a book by John Dee, the Elizabethan magus and court astrologer of Elizabeth I of England, published in Antwerp in 1564. It is an exposition of the meaning of an esoteric symbol that he invented. Dee's Monas Hieroglyphica presents a complex emblem constructed from various astrological symbols, with elements of Latin wordplay, capitalization, spacing, and diacritics, rendering its interpretation challenging. The symbol is intended to embody a profound concept, representing the unity of all creation influenced by celestial forces. Dee believed that this symbol contained the essence of alchemical transformation and spiritual evolution, and by meditating upon it, he aimed to access hidden knowledge transcending linguistic barriers. In merging astrology, alchemy, mysticism, and metaphysics, the Hieroglyphic Monad serves as a visual manifestation of Dee's interconnected worldview. Source: Wikipedia (en)
