"The third is the motion in declination. For, the axis of the daily rotation is not parallel to the Grand Orb's axis, but is inclined [to it at an angle that intercepts] a portion of a circumference, in our time about 23 1/2°. Therefore, while the earth's center always remains in the plane of the ecliptic, that is, in the circumference of a circle of the Grand Orb, the earth's poles rotate, both of them describing small circles about centers [lying on a line that moves] parallel to the Grand Orb's axis." Copernicus, Commentariolus

Even descriptions of the seasons today of the North and South poles from an ecliptic polar view use those circles scribed by polar latitudes with the circles coincident with the Arctic/Antarctic circles, of course, the surface rotation as a function of orbital motion reflects the surface rotation of the entire Earth. Let's not kid ourselves, the strain to hold on to axial precession as a 25900 year event with the actual cause of the seasons using two distinct rotations acting in combination is the central issue.


Separate to all this, the increasing popularity of a pivoting circle of illumination and a planet with a zero degree inclination is alarming, not among a small group of fundamentalists but among mainstream reference conduits such as Wiki or APOD -

The level of discussion belongs with how the precession of the equinoxes is resolved as a further refinement of the leap day correction based on the original astronomical references in terms of a more exact proportion of rotations to an orbital circuit. It returns to the original relationship which Copernicus pointed out between the North/South poles and the central Sun and as small circles scribed by the planet parallel to the orbital plane as a function of the orbital motion of the Earth.
