In that city, where the Dominicans, overwhelmed with attentions, were occupied with making themselves a stronghold in the system of instruction, the Brothers Minor were more than anywhere else tempted to forsake the way of simplicity and poverty.

Francis's warnings had put on such dark and threatening colors that after the famous earthquake of December 23, 1222, which spread terror over all northern Italy, there was no hesitation in believing that he had predicted the catastrophe.[9] He had indeed predicted a catastrophe which was none the less horrible for being wholly moral, and the vision of which forced from him the most bitter imprecations: "Lord Jesus, thou didst choose thine apostles to the number of twelve, and if one of them did betray thee, the others, remaining united to thee, preached thy holy gospel, filled with one and the same inspiration; and behold now, remembering the former days, thou hast raised up the Religion of the Brothers in order to uphold faith, and that by them the mystery of thy gospel may be accomplished.

Who will take their place if, instead of fulfilling their mission and being shining examples for all, they are seen to give themselves up to works of darkness?
Oh! may they be accursed by thee, Lord, and by all the court of heaven, and by me, thine unworthy servant, they who by their bad example overturn and destroy all that thou didst do in the beginning and ceasest not to do by the holy Brothers of this Order."[10] This passage from Thomas of Celano, the most moderate of the biographers, shows to what a pitch of vehemence and indignation the gentle Francis could be worked up.
In spite of very natural efforts to throw a veil of reserve over the anguish of the founder with regard to the future of his spiritual family, we find traces of it at every step.

"The time will come," he said one day, "when our Order will so have lost all good renown that its members will be ashamed to show themselves by daylight."[11] He saw in a dream a statue with the head of pure gold, the breast and arms of silver, the body of crystal, and the legs of iron.

He thought it was an omen of the future in store for his institute.[12] He believed his sons to be attacked with two maladies, unfaithful at once to poverty and humility; but perhaps he dreaded for them the demon of learning more than the temptation of riches.
What were his views on the subject of learning?
It is probable that he never examined the question as a whole, but he had no difficulty in seeing that there will always be students enough in the universities, and that if scientific effort is an homage offered to God, there is no risk of worshippers of this class being wanting; but in vain he looked about him on all sides, he saw no one to fulfil the mission of love and humility reserved for his Order, if the friars came to be unfaithful to it.
Therefore there was something more in his anguish than the grief of seeing his hopes confounded.
