SIGNS COMMANDING AND OBEYING
Any two signs configurated with each other at an equal distance from
the same, or from either equinoctial point, are termed commanding and
obeying, because the ascensional and descensional times of the one are
equal to those of the other, and both describe equal parallels.
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.
