The Karolinus of Egidius Parisiensis, a twelfth/thirteenth-century poem in five books on the life and virtues of Charlemagne, has attracted the interest of a host of scholars, among them, M. J. J. Brial, Gaston Paris, Joseph Bédier, Paul Lehmann, Gaston Duchet-Suchaux, R. B. C. Huygens, and Paul Beichner. Only excerpts, however, have been printed, even though complete publication has been noted as an urgent desideratum. The full text both of the poem proper and of closely related annexes found in the manuscripts is presented hereunder, together with a study of the author and his work.
