Armillary Spheres are models of the celestial sphere based on the Ptolemy theory of the universe with the earth being stationary at the centre. The celestial sphere is imagined as a sphere with the stars fixed onto its interior and the earth at its centre. Although we now know this to be inaccurate, it does not effect the working of the Armillary Sphere since to an observer on Earth the motion of the Sun and Stars appears the same.
The Armillary Sphere was most commonly used in the 16th and 17th Centuries as a teaching instrument to explain the motion of the Sun and stars in relation to the Earth, hence illustrating the basic principles of astronomy and horology.
