第二部·第二十四至二十五则　向赤纬平行与本身的光线

CANON XXIV.

第二十四则。

To direct the Significator with Latitude, wherever it is found, to the Parallels of the Declination.

带纬度的征象星，无论位于何处，向赤纬平行的推运。

First find the declination of the stars, to whose parallel the significator is said to be carried; then in the middle of the table of declination, look up or down the second order of degrees and signs from the significator's place, changing also the latitude in the same manner, as the significator varies in his motion, till you come to the declination of the promittor's star found above the earth; and when you have obtained it, take the right ascension or oblique ascension of that place according to its latitude or longitude, &c. and you will have every thing entirely in the same manner as before explained.

先求出那些星的赤纬，即征象星据说被带到其平行处的那些星；然后在赤纬表的中部，从征象星的位置起，沿第二列的度数与星座向上或向下查找，纬度也随征象星在运动中的变化同样改变，直到找到前面所求得的允诺星的赤纬；得到之后，按该处的纬度或黄经，取该处的赤经或斜升，等等，你就会得到一切，方法完全与前面所讲的相同。

You have the example in Sebastian, King of Portugal, Ferdinand Gonzagius, Cardinal Salviata Zachia, Verospus, Spinells, and others. See likewise the seven nativities, which, for my own purpose, I lately extracted out of Maginus; in all which, by an exact calculation, you will find that the true prorogator of life, when chosen, as the doctrine of Ptolemy teaches, arrived at such a parallel of the declination, at the true time of death. You will know whether the prorogator may fall in the parallels of declination of the stars, by observing the following:

例子见葡萄牙国王塞巴斯蒂安、费迪南多·贡扎加、萨尔维亚蒂·扎基亚枢机、韦罗斯皮、斯皮内利等人。另请看我新近为自己之用从马吉尼书中摘出的七个本命盘；在这一切例子中，经精确计算，你会发现，按托勒密的学说所选定的真正的生命释放星，正是在真实的死亡时刻到达这样一个赤纬平行。要知道释放星是否会落在诸星的赤纬平行上，可观察以下所说：

If the prorogator leaves the tropics, so as to lessen his declination, he will fall on the parallels of those stars, whose declination is less than his; and if, from the equi-nocturnal, on the parallels of greater declination.

若释放星离开回归点，以致赤纬减小，它就会落在那些赤纬比它小的星的平行上；若是离开昼夜平分点，就落在赤纬较大的平行上。

CANON XXV.

第二十五则。

To direct the Significator to the proper Rays in the Zodiac.

征象星向黄道上本身光线的推运。

First mark out the proper ray of the significator longitudinally in the ecliptic, if it be the Sun; or latitudinally, if the Moon, preserving that latitude which it hath in the place of the ray, according to its distance there from its nodes; then take the right or oblique ascension of the aspect longitudinally and latitudinally; work according to the foregoing rule. See an example in Charles V. Mean while, take care that the angles are not directed to the planetary rays in the Zodiac; neither to the parallels, nor the proper rays; for they receive only the rays of the stars taken in the world. These we shall mention in the following part.

先在黄道上标出征象星本身的光线：若是太阳，按黄经标出；若是月亮，按纬度标出，保留它在光线之处按离交点的距离所具有的那个纬度；然后按黄经与纬度取该相位的赤经或斜升；依照前面的规则计算。例子见查理五世。同时要注意，四角不可推向黄道上的行星光线，既不推向平行，也不推向本身的光线；因为它们只接受在世界上所取的星辰光线。这些我们将在下一部讲到。
