“The taste I have always had for the rites and ancient customs of the churches of France has led me to undertake many journeys throughout the provinces of France. I have visited the greater part of the most well-known churches and cathedrals, and I believe that in the course of these journeys I have made some discoveries in ecclesiastical and pagan antiquity that may be of some use to the public and especially to the Church.”
