On the same day on which the "conversos" were freed, the Dominicans displayed a crucifix and a reliquary in glass from which a peculiar light issued in a side-chapel of their church, where several New Christians were present. A New Christian who tried to explain the miracle as due to natural causes was dragged from the church and killed by an infuriated woman. A Dominican roused the populace still more. Friar João Mocho and the Aragonese friar Bernardo, crucifix in hand, were said to have gone through the streets of the city, crying "Heresy!" and calling upon the people to destroy the "conversos". Attracted by the outcry, sailors from Holland, Zeeland and others from ships in the port of Lisbon, joined the Dominicans and formed a mob with local men to pursue the "conversos".
