An astrological discourse with mathematical demonstrations proving the powerful and harmonical influence of the planets and fixed stars upon elementary bodies in justification of the validity of astrology : together with an astrological judgment upon the great conjunction of Saturn & Jupiter, 1603 / written by that worthy, learned gentleman, Sir Christopher Heydon, Knight ; and now published by Nicholas Fiske ...

THis exquisite Treatise having been near 40 years detained in private hands, is now by the good hand of God made publike; it being the One, and only Copy of this Subject extant in the World: Pen'd it was by the incomparably learned Sir Christopher Heydon Knight, whose able Pen hath so strenuously vindicated Judicial Astrologie; as to this day not any Antagonist •••…•••…st encounter with his unanswer able Arguments. In this Tractate that very thing which all Antagonists cry out for, viz. Where's the demonstration of the Art? is hear in this Book by ••••••…••••••…able Mathematical Demonstrations so judiciously proved, that the most scrupulous may receive full satisfaction. I shall ouly add thus much, that we may herein ad∣mire the divine Providence of God, who so long since elevated the Conceptions of this learned Kt, to go on with, to perform and perfect so high and so sublime a piece of learning, and yet deferred its. publication, until both the times, and mens minds also were by his all-guiding hand made capable of its reception: The Work speaks its own merits. I am thine,
