To understand this, we must know that the Stars of the Firmament have their peculiar motions from West to East, upon the Pole of the Eccliptick, and that they go that way a matter of one Degree, in the space of about 100 years, and consequently the Stars do retrograde every year in the Eccliptick from West to East 52 Seconds. _Ptolomeus_ holdeth this opinion, but other renowned Astrologers give them more: For my part I am of _Tychobrahe_’s opinion, who allowed them one Degree of retrogradation in 70 years and 7 Months, and consequently 51 Seconds every year. According to this Doctrine the Star that is in the Horn of _Aries_, was observed by _Tymocharis_ in 2d Degree; 150 years after, _Hipparchus_ observed it in the first; 265 years after, _Ptolomeus_ saw it in the 6 Degree; 740 years after, _Albathognius_ observed it in the 18 Degree; 304 years after, _Alphonsus_ King of _Spain_, found it in the 6 Degree; 265 years after, _Copernicus_ did observe it to be in the 27 Degree and two Minutes; 61 years after, _Tychobrahe_ saw it in the 27 Degree, and above 37 Minutes; so that in the space of 61 years it had gone 35 Minutes. By this Doctrine we see that the whole constellations do not go beyond their Poles, though the Stars that Compound them change their Poles every year of 51 Seconds. To double, then here cannot be taken in the first sense, nor in the third sense, for the first reason, it must then be in the second sense; and thus _Aries doubleth his Bastarnan Pole_; that is, _Aries_ maketh twice his Pole, which answereth to _Bastarnia_. If you ask how it cometh to pass that _Aries_ doubleth this Pole, and in what place of Heaven we set this _Bastarnan Pole_. I answer to the first, that _Aries_ doubleth his Pole, when one of those 13 Stars cometh to that point, which is a Northern or Western Pole to that sign in the Eccliptick. As to the second: I answer, that the place ought to be its last Degree, _viz._ the end of the 30 Degree. Why? (will you say) did the Author mark that difference of the Sign of _Aries_, rather than that of _Taurus_, or of another? I answer, that it was in favour of _France_; because _Aries_ doth govern in _France_, and if it hath been favourable to it, when it came first to the _Bastarnan Pole_, it will be so too when it doubleth the same Pole, seeing that it will have the same position and Aspect. Now we see, that in the space of these 100 years, _France_ was not overcome, much less shall it be hereafter, seeing that the Stars do promise its exaltation for a long continuance. If I were a great Astrologer, I should observe exactly by this, that within the space of 290 years, _Aries shall double his Cape Bastarnan_, and consequently _Aries_ should come to that Pole just in the year 1845. which is according to that we have said.
