Chapter XIX. Signs inconjunct
Chapter 20 of 81
ALL signs, between which there does not exist any familiarity in any of the modes above specified, are inconjunct and separated.
For instance, all signs are inconjunct which are neither commanding nor obeying, and not: beholding each other nor of equal power, as well as all signs which contain between them the space of one sign only, or the spate of five signs, and which do not at all share in any of the four prescribed configurations: viz. the opposition, the trine, the quartile, and the sextile. All parts which are distant from each other in the space of one sign only are considered inconjunct, because they are averted, as it were, from each - other; and because, although the said space between them may extend into two signs, the whole only contains an angle equal to that of one sign: all parts distant from each other in the space of five signs are also considered inconjunct, because they divide the whole circle into unequal parts ; whereas the ‘Spaces contained in the configurations abovementioned, viz. the opposition, trine, quartile, and sextile, produce aliquot divisions*.
is, however, to be recollected, that the parallels now alluded to are distinct from the mundane parallels, which are equal distances from the horizon or meridian, and are considered by Ptolemy in the 14th and 15th Chapters of the $d Book of this work ;—although not under the express name of mundane parallels.
*It has never been very clearly shewn how the followers of Ptolemy have reconciled the new [aspects called the semiquadrate, quintile, sesquiquadrate, biquintile, &c.] with the veto pronounced in this chapter. Kepler is said to have invented them, and they have been universally adopted ; even Placidus,,who has applied Ptolemy’s_ doctrine to practice better than any other writer, has availed himself
