Monas Hieroglyphica

Monas Hieroglyphica ...the science of the alphabet contains great mysteries since He, who is the only author of all mysteries, has compared himself to the first and last letter...How great then must be the mysteries of the intermediate letters? And is it not surprising that this mystery should be so restricted in letters; for all things visible and invisible, manifest and most occult things, emanating (through the medium of nature or art) from God himself, are to be most diligently explored in our wanderings. John Dee, Monas Hieroglyphica, 1564, Preface
