Bruno was buried in the little cemetery of the hermitage of Santa Maria. In 1513, his bones were discovered with the epitaph ""Haec sunt ossa magistri Brunonis"" (these are the bones of the master Bruno) over them. Since the Carthusian Order maintains a strict observance of humility, Saint Bruno was never formally canonized. He was not included in the Tridentine Calendar, but in the year 1623 Pope Gregory XV included him in the General Roman Calendar for celebration on 6 October.
