An armillary sphere is a representation of the antique concept of celestial sphere or orbs, invented by greek philosophers. The Firmament was assimilated to a sphere centered on Earth. During Antiquity and the Middle Ages, the stars were considered as equidistant from the center and an armillary sphere was assumed to be an exact representation of the universe. Even if now know that this model is wrong, it remains a very practical abstraction for the astronomy of position. The exterior parts of this machine are a compages of rings and axes, which represent the principal circles of the heavens:  the polar axis  an horizontal disc representing the horizon of the place  particular parallels as the equator, the 2 polar circles and the 2 tropics  the ecliptic, apparent way of the Sun in the sky The Earth is represented by a ball placed in its center on the polar axis. These machines were used as teaching tools and, for the largest of them, as observation instruments, in particular by Ptolemaeus. The paintings of the scientists and the notables of the Renaissance often show them with a hand on an armillary sphere which represented the top of knowledge and wisdom.
