Astronomia Reformata

Scarce first edition of Riccioli's anti-Copernican, Tychonic geo-centrist cosmology, presenting an astronomy reformed, so he claims, of theoretical as well as observational errors, and considered a conclusion to the Almagestum novum of 1651. As the Jesuits' leading astronomer, his observational and experimental achievements offered significant refinements of Galilean quantitative experimental procedures in terms of accuracy, and although intended to refute Galileo, his results often unwittingly confirmed them.
