《Tetrabiblos》Application, Separation, And Other FacultiesClaudius Ptolemy（Ashmand 英譯 1822）
The following definition of an aspect, by Kepler, strengthens my opinion: “An aspect is an angle formed on the earth, by the luminous rays of two planets; efficacious in stimulating sublunary nature.” It appears, therefore, by the whole of what has been already delivered, that the effective influence of the stars must be considered as arising not only from their own peculiar natures and properties, but also from the quality of the surrounding signs, and from configuration with the Sun and the angles; all which has been pointed out.
