《Tetrabiblos》Signs Commanding And ObeyingClaudius Ptolemy（Ashmand 英譯 1822）
The signs in the summer semicircle are commanding; those in the winter semicircle, obeying: for, when the Sun is present in the former, he makes the day longer than the night; and, when in the latter, he produces the contrary effect.
