As David Ovason reveals, many leading esoteric writers - alchemists, occultists and Rosicrucians -contributed to this 'Secret booke'. Among the more outstanding English literary figures who used the code were the mysterious adviser to Elizabeth I, John Dee, the turbulent author of The Alchemist, Ben Jonson, and the more classically-minded Edmund Spenser, whose poem 'The Faerie Queene' is the best-known esoteric work of the period. Shakespeare's Secret Booke reveals many other literary figures who together form a remarkable underground literary movement, including the most influential esotericist of the period, Jacob Boehme, and alchemists such as the English polymath Robert Fludd. Another was Shakespeare's contemporary, the youthful Johann Valentin Andreae, credited as author of The Chymical Wedding - a Rosicrucian work replete with sophisticated examples of encoding. --
