Euclid reviewed by Legendre, or from the ``Elements'' to the ``Elements of geometry'' (Q2917734)

This is a very readable survey of the impact of Euclid's \textit{Elements}, containing several interesting quotes, some from rather unlikely sources -- such as Sully Prudhomme or Abraham Lincoln -- on the significance of Euclid's \textit{Elements}, what little we know about Euclid and his works, the content of the \textit{Elements}, its transmission, including adaptations and pedagogical variants, to end with Legendre's \textit{Éléments de géométrie} -- a textbook that dominated the teaching of elementary geometry in French-speaking countries (the Belgian case is given closer scrutiny) and in the United States, all the way up to the reform that emphasized modern mathematics -- and Hadamard's \textit{Leçons de géométrie élémentaire}.
