Note 4 — INTRODUCTION.1

Since this paper first appeared many important researches have been made on the origin of Florence and its Commune, particularly by Professor D. O. Hartwig, of whose estimable work we shall speak later on. Several general histories of Florence have also been published, of which the more noteworthy are the "Storia della Repubblica di Firenze," by the Marquis Gino Capponi (Florence, Barbera, 1875, 2 vols.), and "L'Histoire de Florence," by Mons. Perrens (Paris, 1877–90, 9 vols.), both to be mentioned farther on.
