Con Cicerón por los caminos (zigzagueantes) de la amistad

Considerations about the evolution of the concept of “friendship”, just as Cicero understands it, along the history (individual, social, political and religious friendship). Repetitions and interpretations of his definition and of other ciceronian texts. His influence on several authors (such as Augustinus, Isidorus Hispalensis, Ra-banus Maurus, Petrus Venerabilis) and, above all, on the mediae-val treaties De amicitia written by Aelredus Rievallensis and Petrus Blessensis
