“…one day St. Paulinus saw in a dream a field in which bluebells grew. When the bishop picked the bell, it rang, after which a voice was heard: ‘And you do likewise.’ The next morning, St. Paulinus ordered to cast a bell in the shape of a flower. This was the beginning of the tradition of bell ringing in Europe.”
