Chapter XIII. Of a certain vision
20. Before his conversion a certain devout brother had seen concerning this church a vision that is worth relating. He saw countless men smitten with woful blindness kneeling round this church with their faces lifted toward heaven: and they were all stretching their hands upward and crying with lamentable voice to God, asking for mercy and light. And lo! there came a great brightness from heaven and spread itself over them all, giving light and longed-for healing to each one.
