*Girolamo Saccheri*

“In this book Girolamo Saccheri set forth in 1733, for the first time
ever, what amounts to the axiom systems of non-Euclidean geometry. It is in
this book that, for the first time in history, theorem after theorem of
(hyperbolic) non-Euclidean geometry is stated and proved. Why—one
cannot help asking–did Saccheri not evaluate correctly what he had
achieved, why did he not claim credit for the discovery of non-Euclidean
geometry?… The main content of the Notes are a series of annotations to
Saccheri's text by the eminent scholars Paul Stäckel and Friedrich
Engel. These annotations originally appeared as footnotes to these
authors' German translation of *Euclides Vindicatus* and were, with
some modifications, translated into English by F. Steinhardt.”
