Doctor Faustus having received denial of his Spirit, to be resolved any more in such-like questions propounded; forgot all good works, and fell to be a Calendar maker by help of his Spirit; and also in short time to be a good Astronomer or Astrologian: he had learned so perfectly of his Spirit the course of the Sun, Moon, and Stars, that he had the most famous name of all the Mathematicks[20] that lived in his time; as may well appear by his works dedicated unto sundry Dukes and Lords: for he did nothing without the advice of his Spirit, which learned him to presage of matters to come, which have come to pass since his death. The like praise won he with his Calendars, and Almanacs making, for when he presaged upon any change, Operation, or alteration of the weather, or Elements; as wind, rain, fogs, snow, hail, moist, dry, warm, cold, thunder, lightning: it fell so duly out, as if an Angel of heaven had forewarned it. He did not like the unskilful Astronomers of our time, that set in Winter cold, moist, airy, frosty; and in the Dog-days, hot, dry, thunder, fire, and such-like: but he set in all his works, day and hour, when, where, and how it should happen. If anything wonderful were at hand, as death, famine, plague, or wars, he would set the time and place in true and just order, when it should come to pass. [Footnote 20: i.e. Mathematicians.] CHAPTER XVIII _A question put forth by Doctor Faustus to his Spirit concerning Astronomy_ Doctor Faustus falling to practice, and making his Prognostications, he was doubtful in many points: wherefore he called unto him Mephostophiles his Spirit, saying: I find the ground of this science very difficult to attain unto: for that when I confer Astronomia and Astrologia, as the Mathematicians and ancient writers have left in memory, I find them to vary and very much to disagree: wherefore I pray thee to teach me the truth in this matter. To whom his Spirit answered, Faustus, thou shalt know that the practitioners or speculators, or at least the first inventors of these Arts, have done nothing of themselves certain, whereupon thou mayest attain to the true prognosticating or presaging of things concerning the heavens, or of the influence of the Planets: for if by chance some one Mathematician or Astronomer hath left behind him anything worthy of memory: they have so blinded it with Enigmatical words, blind Characters, and such obscure figures; that it is impossible for an earthly man to attain unto the knowledge thereof, without the aid of some Spirit, or else the special gift of God; for such are the hidden works of God from men: yet do we Spirits that fly and fleet in all Elements, know such, and there is nothing to be done, or by the Heavens pretended, but we know it, except only the day of Doom. Wherefore (Faustus) learn of me, I will teach thee the course and recourse of ♄. ♃. ♂. ☉. ♀. ☿ and ☽.[21] the cause of winter and summer, the exaltation and declination of the
