Wadding thought it his duty to give a place in his collection to several suspicious pieces; more than this, instead of following the oldest manuscripts that he had before him, he often permitted himself to be led astray by sixteenth-century writers whose smallest concern was to be critical and accurate. To avoid the tedious and entirely negative task to which it would be necessary to proceed if I took him for my starting-point I shall confine myself to a positive study of this question. All the pieces which will be enumerated are found in his collection. They are sometimes cut up in a singular way; but in proportion as each document is studied we shall find sufficient indications to enable us to make the necessary rectifications. The archives of Sacro Convento of Assisi[5] possess a manuscript whose importance is not to be overestimated. It has already been many times studied,[6] and bears the number 338. It appears, however, that a very important detail of form has been overlooked. It is this: that No. 338 is not _one_ manuscript, but _a collection_ of manuscripts of very different periods, which were put together because they were of very nearly the same size, and have been foliated in a peculiar manner. This artificial character of the collection shows that each of the pieces which compose it needs to be examined by itself, and that it is impossible to say of it as a whole that it is of the thirteenth or the fourteenth century. The part that interests us is perfectly homogeneous, is formed of three parchment books (fol. 12a-44b) and contains a part of Francis's works. 1. The Rule, definitively approved by Honorius III., November 20, 1223[7] (fol. 12a-16a). 2. St. Francis's Will[8] (fol. 16a-18a). 3. The Admonitions[9] (fol. 18a-23b). 4. The Letter to all Christians[10] (fol. 23b-28a). 5. The letter to all the members of the Order assembled in Chapter-general[11] (fol. 28a-31a). 6. Counsel to all clerics on the respect to be paid to the Eucharist[12] (fol., 31b-32b). 7. A very short piece preceded by the rubric: "Of the virtues which adorn the Virgin Mary and which ought to adorn the holy soul"[13] (fol. 32b). 8. The _Laudes Creaturarum_, or Canticle of the Sun[14] (fol. 33a). 9. A paraphrase of the _Pater_ introduced by the rubric: _Incipiunt laudes quas ordinavit. B. pater noster Franciscus et dicebat ipsas ad omnes horas diei et noctis et ante officium B. V. Mariae sic incipiens: Sanctissime Pater_[15] (fol. 34a). 10. The office of the Passion (34b-43a). This office, where the psalms are replaced by several series of biblical verses, are designed to make him who repeats them follow, hour by hour, the emotions of the Crucified One from the evening of Holy Thursday.[16] 11. A rule for friars in retreat in hermitages[17] (fol. 43a-43b).
