Monas Hieroglyphica

John Dee wrote Monas Hieroglyphica at Antwerp in 1564. In twenty-four compact theorems, he joins point, line, circle, the Sun and Moon, planetary characters, formal numbers, alchemical operations, Christian Cabala, and a single compound sign. Each theorem carries earlier shapes and terms into a new use, which makes the exact wording and placement of the figures part of the argument. This edition translates the Antwerp Latin directly into modern English. It preserves the source order, meaningful capitals, technical names, mathematical relations, Greek forms, and open syntax where a smoother phrase would narrow the sense. The digitized Wellcome copy controls the reading. Another copy of the same 1564 edition supports collation, while its machine text serves only as a locating aid. What this new translation includes: - All twenty-four theorems in source order - Twenty-six source figures with captions and descriptions - Historical orientation, linked notes, glossary, sources, and index - Direct checking against the 1564 Wellcome witness All twenty-six source figures remain beside the parts of the work they serve. Captions identify each source locus, concise alternatives describe the visible structure, and original geometric reconstructions make the densest diagrams readable at a small size. Damaged words, uncertain labels, and source-language problems are marked openly. One Hebrew formula remains a clearly labelled publication hold pending qualified review. A historical orientation sets Dee's dedication to Maximilian and his instructions to printer Willem Silvius within the dates of the Antwerp production. A compact guide traces geometry, number, planetary signs, alchemical language, and Cabala without treating them as interchangeable. Linked translation notes, a detailed glossary, sources, a list of figures, and an index support close reading without claiming that the whole Monad has one settled decoding. For readers of Renaissance intellectual history, Western esotericism, alchemy, the history of mathematics, and early printing. Read the theorems in order, follow each sign through its changing roles, and consult the linked apparatus whenever a difficult term or figure requires context.
