THE INTRODUCTION.

FOr their sakes that (as yet) understand no∣thing of this kind of Learn∣ing, I thought good to pre∣mise this by way of Introdu∣ction to the right under∣standing and application of the following Work.

1. They ought to acquaint themselves with the right use of an Ephemeris (which they may have annually for a smal price.) To which purpose, after they understand the Characters of the seven Pla∣nets, the twelve Signs, and those of the Aspects (which are the only furniture of an

Ephemeris) they should also learn to know the distance of each Aspect in the Eclip∣tick, or Zodiack, which is briefly shewed in the follow∣ing Work.

2. To be exceeding ready, by the help of their Epheme∣ris, to discover what Pla∣nets are in Configuration the one with the other; as also how the Moon beholds them, as she passeth through the Zodiack.

3. Learn to be well ac∣quainted with the Nature of the Signes; as which are Fiery, which Earthy, which Aery, and which Watery.

4. Be careful to observe the several Separations and Applications of the Planets;

as also their Natures, and ••he Nature of the fixed Stars, by whose bodies they frequently pass, in their Di∣urnal and Annual Motions. I say, these (and such like things as these) are neces∣sary to be known by all such as desire to be acquainted with this kind of sublime ••nowledg, which leads to ••he contemplation and admi∣••ation of the great and won∣derful Works of our Creator.

Now those that are as yet Strangers to this kind of Study, may (if they please) acquaint themselves with the Fundamentals of Astro∣logy, by the help of a small Treatise lately published, en∣tituled Clavis Astrologiae, to be sold at the Raven in

Duck-lane; wherein they shall receive full satisfacti∣on in what is convenient to be known by way of intro∣duction to this Art; as also the Genethliacal part of Astrology, viz. the exact handling and calculating Nativities, and other things of good use to all such whose Genius leads them to this kind of Speculation. Lastly, Note that it is the opinion of some good Artists, and curious Observators, that not only the Geocentrick A∣spects ought to be considered, but also the Heliocentrick Aspects of the Planets, which are found to cause much variation in the Weather, when there hath been nothing to signifie the same other∣wise, Vale.
