“ This organization, at least in so far as concerns the heretical church, had already been observed among the Fraticelli in Sicily, and in 1423 the general council of Siena affirmed with horror that at Peniscola there was an heretical pope surrounded with a college of cardinals who made no attempt at concealment. From 1426 to 1449 the Fraticelli were unremittingly pursued, imprisoned and burned. The sect gradually died out after losing the protection of the common people, whose sympathy was now transferred to the austere Observants and their miracle-worker Capistrano. ”
