ANTIQUE ARMILLARY SPHERE
An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (in the celestial sphere),
consisting of a spherical framework of rings, centred on Earth or the Sun, that represent lines of celestial longitude and latitude
and other astronomically important features such as the ecliptic. As such, it differs from a celestial globe, which is a smooth sphere
whose principal purpose is to map the constellations. It was invented separately in ancient Greece and ancient China,
with later use in the Islamic world and Medieval Europe.
