Publisher's Synopsis
This book, "Die Theorie der Parallellinien von Euklid bis auf Gauss eine Urkundensammlung zur Vorgeschichte der nichteuklidischen Geometrie, in Gemeinschaft mit Friedrich Engel", by Paul Stäckel, is a replication of a book originally published before 1895. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible.
