The works of St Francis consist of the Rule (in two redactions), the Testament, spiritual admonitions, canticles and a few letters. They were first edited by Wadding in 1623. Two critical editions were published in 1904, one by the Franciscans of Quaracchi near Florence, the other (in a longer and a shorter form) by Professor H. Boehmer of Bonn. Sabatier and Goetz (see below) have investigated the authenticity of the several works; and the four lists, while exhibiting slight variations, are in substantial accord. Besides the works, properly so called, there is a considerable amount of traditional matter--anecdotes, sayings, sermons--preserved in the biographies and in the _Fioretti_;[1] a great deal of this matter is no doubt substantially authentic, but it is not possible to subject it to any critical sifting. _Note on Sources._--The sources for the life of St Francis and early Franciscan history are very numerous, and an immense literature has grown up around them. Any attempt to indicate even a selection of this literature would here be impossible and also futile; for the discovery of new documents has by no means ceased, and the criticism of the materials is still in full progress, nor can it be said that final results have yet emerged from the discussion. Students will find the chief materials in the following collections: _Archiv fuer Litteratur und Kirchengeschichte des Mittelalters_ (ed. by Ehrle and Denifle, 1885, &c.); publications of the Franciscans of Quaracchi (list to be obtained from Herder, Freiburg im Breisgau); and the two series edited by Paul Sabatier, _Collection d'etudes et de documents sur l'histoire religieuse et litteraire du moyen age_ (5 vols. published up to 1906) and _Opuscules de critique historique_ (12 fascicules): the easiest and most consecutive way of following the controversy is by the aid of the "Bulletin Hagiographique" in _Analecta Bollandiana_. Relatively popular accounts of the most important sources are supplied in the introductory chapters of Sabatier's _Vie de S. Francois_ and _Speculum perfectionis_, and Lempp's _Frere Elie de Cortone_.
