One other event will complete the record of John's Pontificate, before we begin the story of his undoing. The abuses of the Roman Curia had excited, or encouraged, various hostile movements. There were Lollards in England, and followers of Hus and Jerome of Prague in Bohemia. These vague and unimportant movements--from the Papal point of view--were left to local prelates, but the growing Christian demand for another General Council was disquieting. The Council of Pisa had put itself above the Popes, and grave doctors at many universities argued that a council must effect that reform of the Church which Popes refused to effect. Probably John XXIII. did not appreciate the full significance of this Conciliar movement, but he did see that there was grave danger that a Council would depose him, as well as Benedict and Gregory, unless he controlled it. He, therefore, in 1412, announced that a General Council would be held at Rome, and he reminded prelates that the Council of Pisa had enjoined this. But only a few French and Italian prelates responded to his summons, and a strange accident increased his uneasiness. One day, when all were assembled in St. Peter's, a screech owl issued from a dark corner and perched opposite the Pope. John reddened and perspired, as he gazed into the uncanny eyes of the bird, and at last he left his seat and broke up the sitting. It was there again at the next sitting, and was killed only after a great commotion. A strange form for the Holy Ghost, the mockers said; a dreadful omen for the Pope, said others. Reforms were promised, and the works of Wyclif were condemned, but the Council was too small to have effect and it was prorogued until December 1, 1413.
