This classic book is Charles Lutwidge Dodgson’s 1879 work, “Euclid and his Modern Rivals”. It is a mathematical volume that compares thirteen contemporary geometry textbooks, describing each one in relation to its superiority or inferiority to “Euclid's Elements”. This volume will appeal to those with a keen interest in mathematical education, and would make for a wonderful addition to collections of allied literature. Contents include: “Preliminaries to Examination of Modern Rivals”, “A Priori reasons for retaining Euclid’s Manual”, “Manuals which reject Euclid’s Treatment of Parallels”, “Treatment of Parallels by Methods involving Infinite Series”, “Treatment of Parallels by Angels made with Transversals”, etc. Many classic books such as this are becoming increasingly rare and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author.
