Fourthly, We must suppose that this word to double, may signifie three things.
1. In Sea-mens tearms; it signifieth to go beyond some place, as to double the Cape of bona Speranza, which is called in Italian, Tramontare; that is, to go beyond.
2. It signifieth to do twice the same thing, as Jacob did double his service for Ra∣chel, &c. 3. In matter of traveling; it signifieth to go twice as far as is requi∣site.
To double, in this place cannot be understood in the first sense; because the con∣stellations never stretcht out of their compasses, though the Stars of which they are compounded, have their peculiar motions.
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 con∣sequently 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 De∣gree 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 Ba∣starnan Pole; that is, Aries maketh twice his Pole, which answereth to Bastar∣nia.
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 ex∣altation 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
