These Books were written near seventeen years since, and preserved by the good hand of God in the custody of Mr. Thomas Heydon, Sir John Hanner, Sir Ralph Freman, and Sir Richard Temple; during the tyrant's time first one had the Books, then another, etc. And at last at the desire of these Noble, Learned and valiant Knights, and in honour of his Highness the Duke of Buckingham, they were printed. He wrote many excellent things, and performed many rare experiments in the Arts of Astromancy and Geomancy, etc., but especially eighty one, the first upon the King's death, predicted in Arabia by him to his friends, the second upon the losses of the King at Worcester, predicted at Thauris in Persia. Thirdly he predicted the death of Oliver Cromwell in Lambeth House to many persons of honour mentioned in his books. Fourthly he wrote of the overthrow of Lambert, and of the Duke of Albymarle, his bringing again of the King to his happy countries, and gave it to Major Christopher Berkenhead, a Goldsmith at the Anchor by Fetter Lane end in Holborn; the fifth precaution or prediction he gave to his highness the Duke of Buckingham, two months before the evil was practised, and his enemy Abraham Goodman lies now in the Tower for attempting the death of the noble Prince. The sixth for Count Gramont when he was banished into England by the King of France, and he predicted by the Arts of Astromancy and Geomancy, the King's receiving again into favour, and of his marriage to the Lady Hamilton. The seventh for Duke Minulaus, a peer of Germany, that the Emperor sent to him, when the Turk, had an army against him, and of the death of the Pope; the rest are in his books, and therefore by these monuments the name of Heydon for his variety of learning was famous not only in England, but also in many other nations into which his books are translated. This John Heydon, fears none, contemneth none, is ignorant of none, rejoyceth in none, grieves at none, laughs at none, is angry with none, but being himself a Philosopher, he hath taught the way to happiness, the way to long life, the way to health, the way to wane young being old, and the way to resolve all manner of Questions, Present and to Come, by the Rules of Astromancy and Geomancy, and how to raise the Dead.
