CLAUDIUS PTOLEMY:

TETRABIBLOS

OR THE QUADRIPARTITE MATHEMATICAL TREATISE

16. Of Disjunct Signs.

" Disjunct" and" alien" are the names applied to those divisions of the zodiac which have none whatever of the aforesaid familiarities with One another. These are the Ones which belong neither to the class of commanding or obeying, beholding or of equal power, and furthermore they are found to be entirely without share in the four aforesaid aspects, opposition, trine, quartile, and sextile, and are either One or five signs apart; for those which are One sign apart are as it were averted from One another and, though they are two, bound the angle of One, and those that are five signs apart divide the whole circle into unequal parts. while the other aspects make an equal division of the perimeter.
