celestial axis

The celestial axis is the line connecting the celestial poles.

Altitude dials measure the height of the sun in the sky, rather than its rotation about the celestial axis.

For illustration, the celestial axis points vertically at the true North Pole, where it points horizontally on the equator.

In the equatorial bow sundial, the gnomon is a bar, slot or stretched wire parallel to the celestial axis.

Eon's history stretches back into the universe's infancy; he is the offspring of Eternity and Infinity and the Celestial Axis.

His equivalent in Latin poetry-though he scarcely makes an appearance in Roman mythology-was Polus, the embodiment of the celestial axis around which the heavens revolve.

Thus, he was Atlas Telamon, "enduring Atlas," and became a doublet of Koios, the embodiment of the celestial axis around which the heavens revolve.

Following the example of Villard, Peter of Maricourt designed a magnetic globe which, if it were mounted without friction parallel to the celestial axis, would rotate once a day.

Since the celestial axis is aligned with the axis about which the Earth rotates, the angle of the axis with the local horizontal is the local geographical latitude.

A linear gnomon aligned with this axis will cast a sheet of shadow (a half-plane) that, falling opposite to the Sun, likewise rotates about the celestial axis at 15 per hour.

For the purposes of a sundial, an excellent approximation assumes that the Sun revolves around a stationary Earth on the celestial sphere, which rotates every 24 hours about its celestial axis.

Charged with protecting the Celestial Axis (the pattern of life energy threading through the universe), and Time, although it often chooses to observe our reality while removed in a dimension called 'The Mists of Time'.

If the shadow falls on a surface that is symmetrical about the celestial axis (as in an armillary sphere, or an equatorial dial), the surface-shadow likewise moves uniformly; the hour-lines on the sundial are equally spaced.

The bare facts of the story are these: The system of Aristotle and Ptolemy, which placed the earth motionless at the center of the cosmos, explained the movement of the sun and stars across the sky as a daily rotation of the heavens about a celestial axis.

The "dragon" is often understood as the starry constellation Draco and by extension it represents the cosmic axis (equivalent to the north/south pole) because this constellation coils around the North Star and thus around the celestial axis, as it intersects the northernmost part of the celestial sphere.
