Euclidis Elementorum Libri Priores Sex, Item Undecimus Et Duodecimus est opus geometricum, quod a Simson, Roberto, mathematico celeberrimo, anno MDCCXLV editum est. In hoc libro, Euclides, mathematicus Graecus, quattuordecim propositiones geometricas, quae in prioribus sex libris Elementorum contineri non poterant, praebet. Simson, in hac editione, textum Euclidis accuratissime recensuit, et adnotationibus et demonstrationibus suis illustravit. Praeterea, librum adornavit diagrammatibus elegantissimis, quae ad intelligendum et demonstrandum proposita Euclidis valde utiles sunt. Hoc opus, non solum mathematicis, sed etiam philosophis et ingeniosis omnibus, qui disciplinam geometricam amant, utile est.This Book Is In Latin.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
