But I need not tell you that there are also marvels within my books — among them wonderful and rare works by Zoroaster, Orpheus, and Hermes Trismegistus, as well as the sheets of old ephemerides. This room has become a very university or academy for scholars of diverse sorts, and there are such writings here as are above price, viz. Reuchlin his De verbo mirifico and De arte cabalistica, Brunschwick's Book of Distillation, The New Pearl of Great Worth set forth by Petrus Bonus of Pola but newly edited by Janus Lacinius, Cornelius Agrippa his renowned De occultia philosophia, De incantationibus by Pomponazzi, the Corpus Hermeticum collected by Turnebus as well as Clavicula Solomonis and The Sun of Perfection, which are both very useful and pleasant to read. Nor can I forget that most precious jewel of other men's labours which I have yet recovered, Trithemius his Steganographia. Neither will I omit the wonderful and divine sciences which are published forth by Paracelsus himself, or the connections therewithal to be traced through De harmonia mundi of Francesco Giorgi, De institutione musicae of Boethius, and Paciolus his De divina proportione. These are not to be found for money at any market or in any stationer's shop, since in truth they are works for secret study.
Among these bound volumes lie fair copies of my own writings which, for the everlasting memory of men, are marked with my London seal of Hermes. I have not spent these many years in composing riddles or merry tales, but have rather thought continually of the generations yet to come. And just as the levels of the cosmos are to be known as elemental, intellectual and celestial, so have I placed my own works in varying degrees of art: from those which are suited to the best understanding of mechanics, such as The Elements of Geometry and Mathematical Preface (here I include General and Rare Memorials Pertaining to the Perfect Art of Navigation, together with sundry volumes in horology, perspective, geometry and other arts), to those which are framed for the comprehension of the wise, such as my Propodeumata Aphoristica, leading ever upwards to those most excellent and valuable studies which I keep here beside me and are known only as Liber Mysteriorum. The scope of my enterprise is so great that, as to this time, it has never to my knowledge by any been achieved; that is why I must keep my papers in closed chests within my study, away from the eyes or tongues of vulgar sophisters. It is hard in these our dreary days to win any due or common credit for work in rare arts: so, since I can in no way rely upon the testimony of my countrymen, I join myself here with my ancestors and place my own work beside theirs. When I consider the rash, lewd, fond and most untrue fables conceived of me and my philosophical studies, I find my refuge from bleating tongues here in my library where all the ages lie silently before me. It is my quietus est, my pass-port (as they say) to freedom. Where is liberty to be found but in the memory and the contemplation of the past?
Of course not all is known or can be known, and even of our own kingdom much is lost, yet I have by me here Historia Regum Britanniae, together with various manuscripts concerning the past of Britain collected by Nennius and Geoffrey of Monmouth. I once had a book — I do not know what has become of it because it was taken from me when I was clapped up in the Tower as a conjuror, but I can see it now before me. It was a short, thick old volume with two clasps, printed anno 1517, and it gave some account of the ancient places long buried within this island and now so many lost cities under ground. That wonderful book was stolen, as I say, but the loss is as nothing compared with the general destruction and burning and spoiling of so many notable libraries in the reign of King Henry; the whole stock and store of our past was close to utter extinction, and our antique learning was used to serve the jakes, or scour candlesticks, or rub boots. What I have kept and preserved here are the notable jewels which I have found scattered across the land, so that in this library lies something of the treasure of Britain's antiquity, the everlasting seeds of its continual excellence, the remnants of a once incredible store of the passing excellent work of our forefathers. To Britain's shore once came the giants and, afterwards, those who escaped from the deluge of Atlantis. Their great truths must never be forsaken.
That is why, in order to become a very excellent scholar and a learned man, it is necessary to find the path towards learning through books; otherwise it were as well to be a sophister, a quack or an empiric rather than a philosopher. There are those who say that learning effeminates a man, dims his sight, weakens his brain and engenders a thousand diseases; Aristotle himself tells us, 'Nulla est magna scientia absque mixtura dementiae', which is as much as to say, 'There is no excellent knowledge without mixture of madness'. But I deny even Aristotle in this, since he who has learning holds the flower of the sun, the perfect ruby, the elixir, the magisterium. It is the true stone, the home of the glorified spirit, the virtue of the soul of the world.
Books do not perish like humankind. Of course we commonly see them broken in the haberdasher's shop when only a few months before they lay bound on the stationer's stall; these are not true works, but mere trash and newfangleness for the vulgar. There are thousands of such gewgaws and toys which people have in their chambers, or which they keep upon their shelves, believing that they are precious things, when they are the mere passing follies of the passing time and of no more value than papers gathered up from some dunghill or raked by chance out of the kennel. True books are filled with the power of the understanding which is the inheritance of the ages: you may take up a book in time, but you read it in eternity. Look upon this text here, Ars Notoria, perfected from the Greek by Master Matthew — note how every word signifies the quiddity of the substance, and how every sentence signifies its form. What learning this is (even in a latter and doting age of the world) when every line may reveal how the secret and unknown forms of things are knit up in their originals! Yet this is not for those with mere cabbalistical brains, who see nothing but mysteries and read nothing except to fall upon some revelation; out of one root comes the wild olive as well as the sweet, and these men do nothing more than gape and whisper 'Micma' or 'Fisis' or 'Gohulim' without understanding the meaning of the sacred names.
