Liber qui inscribitur ""Euclides Vindicatus"" auctore Girolamo Saccheri (anno 1920) est tractatus mathematicus qui disputat de geometria Euclidis. Saccheri, mathematicus Italicus, in hoc libro argumentum proponit quod Euclides quaedam axiomata non satis perspicue explicavit, quae tamen necessaria sunt ad demonstrationes geometricas perficiendas. Saccheri, igitur, proponit novas axiomata, quae, ut ipse putat, melius explicant geometriam Euclidis. Hic liber est consideratus ut una ex primis tentationibus non-Euclidianae geometriae, quae postea invenit fuisse fundamentum geometriae Riemannianae.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
