"St. Francis of Assisi (d. 1226): There will be an uncanonically elected pope who will cause a great Schism, there will be divers thoughts preached which will cause many, even those in the different orders, to doubt, yea even agree with those heretics which will cause My order to divide, then will there be such universal dissentions and persecutions that if these days were not shortened even the elect would be lost"
For your consideration. There have been others as well.
