《Tetrabiblos》Number Of The Modes Of ProrogationClaudius Ptolemy（Ashmand 英譯 1822）
For should those places be situated within the terms of a benefic, the operation of their anæretic degree becomes impeded; and it will likewise be impeded, if either of the benefics should cast a ray in quartile, trine, or opposition,[151] to the said anæretic degree itself, or to some other degree near in succession, and not farther distant from it than twelve degrees, if the benefic be Jupiter; nor than eight, if Venus: the like impediment will also subsist, if both the prorogator and its opponent[152] should be bodies,[153] and not have the same latitude.
