Image title
Italian armillary sphere, by Joannes Paolo Ferreri, Rome, 1624. AST0634."An armillary sphere is a three-dimensional model of the Universe used for teaching and, sometimes, for calculation. Some, like this one, are Ptolmaic spheres with the Earth at the centre and the Sun orbiting round it. Copernican spheres have the Sun at the centre. The outer sphere indicates the location of stars."
