We can say then that a star of a certain declination will rise or set at such an azimuth, if we reckon from the N. point of the horizon, or at such an amplitude if we reckon from the equator. This will apply to both north and south declinations.

The following table gives for Thebes the amplitudes of rising or setting (north or south) of celestial bodies having declinations from 0° to 64°; bodies with higher declinations than 64° never set at Thebes if they are north, or never rise if they are south, as the latitude (and therefore the elevation of the pole) there is nearly 26°.
