A Celestial Globe of six feet diameter 

“...The globe itself is Brazen, exactly round and smooth: The stars well made, and in their true places, and all the Circles of a proportionable breadth and thickness. It is besides so well hung that the least touch moves it, and tho it is above two thousand weight the least Child may elevate it to any Degree. On its large concave basis rest in an opposite Station four Dragons, whose Hair standing up an end, support a noble Horison commendable by its Breadth, its several Ornaments, and the Delicacy and Niceness of the Work. The Meridian in which the Pole is fixed, rests upon Clouds that issue out of the Basis, and slides easily between them, its motion being facilitated by some hidden Wheels, and moves with it the whole Globe to give it the required Elevation...These Machines being most of them above 10 feet from the ground, have for the Astronomers greater conveniency, Marble Steps around them, cut Amphitheater-wise.”
