The Libro de Alexandre is an epic poem about the life of Alexander the Great, written by an anonymous Spanish cleric in the thirteenth century. It is the most substantial poem (and almost certainly the first) composed in the learned cuaderna vía verse form and provides a unique insight into the intellectual world from which it sprang.

Many books were written in the Middle Ages about Alexander the Great and still more books have been written about those books in the last hundred years. In this classic study of the medieval Alexander, first published in 1956, George Cary approached the problem from an altogether different angle, using material which none of his predecessors had exploited. He asked himself the simple question: What did people really think about Alexander in the Middle Ages? The resultant answers proved various and unexpected, changing from age to age and from group to group. Published posthumously, Cary's study was edited by D. J. A. Ross, who corrected certain details, added some footnotes and included an additional section on the Histoire ancienne jusqu'a Cesar. To this were also added a number of illustrative plates and an appendix on the origins of the Greek Alexander Romance.
