This book aims to make a new contribution to the knowledge on writings of the great humanists of the fifteenth and sixteenth centuries. Certainly, the volume on the exchange of letters between Bude and Vives is thin: it has only ten letters. Despite the small number, these letters undeniably bring an interesting testimony to the intellectual life or, in the case of Bude, on life itself of the humanists. All letters are accompanied by an exhaustive commentary and a French translation, as well as an index fontium and an index nominum.
