B.Fr._ M.K.
Mueller of Halle, in his _Anfaenge_, has made a very remarkable study of the Rule of 1221, whence he deduces an earlier Rule, which he believes to be that of 1209 (1210).

For once I find myself entirely in accord with him, except that the Rule thus reconstructed (Vide _Anfaenge_, pp.

14-25, 184-188) appears to me to be not that of 1210, which was very short, but another, drawn up between 1210 and 1221.

The _plures regulas fecit_ of the 3 Soc., 35, authorizes us to believe that he made perhaps as many as four--1st, 1210, very short, containing little more than the three passages of the vocation; 2d, 1217 ( ?), substantially that proposed by M.Mueller; 3d, 1221, that of which we shall speak at length farther on; 4th, 1226, the Will, which if not a Rule is at least an appendix to the Rule.

If from 1221-1226 he had time to make two Rules and the Will, as is universally admitted, there is nothing surprising in his having made two from 1210-1221.
