《Tetrabiblos》Knowledge May Be Acquired By Astronomy To A Certain ExtentClaudius Ptolemy（Ashmand 英譯 1822）
The power of the Sun however predominates, because it is more generally distributed; the others either co-operate with his power or diminish its effect: the Moon more frequently and more plainly performs this at her conjunction, at her first and last quarter, and at her opposition: the stars act also to a similar purpose, but at longer intervals and more obscurely than the Moon; and their operation principally depends upon the mode of their visibility, their occultation and their declination.
