What follows is an index of references to the Constitutions of 1260, with an indication of the original date of those which can be dated, and brief notes on a few not discussed in the text of this book. The principles of dating have been discussed above (esp. pp. 212 ff.); pages containing evidence for the dates of individual constitutions are given in italics here. Some even of those most securely dated may, of course, have been later revised, and many of the dates are extremely tentative (but see p. 213). Two points should perhaps be emphasised. (1) Constitutions could only be passed in General Chapter, and so virtually all the constitutions must belong to the years 1239, 1242, 1244, 1247, 1251 (?), 1254, 1257, 1260. Thus if a constitution was probably later than 1252 but earlier than 1260, it can be dated tentatively 1254 or 1257 (cf. c. xi, 21). (2) Constitutions more closely connected with the earlier than the later Dominican recension were probably passed in 1239 (see pp. 227–8). Where the Franciscan texts agree with slight revisions made by the Dominicans in 1239–41, the Franciscans were probably again the borrowers, and the debt was incurred in 1241 or later.
