Attention in this final chapter is directed to the private passions of church personnel as revealed in the executors’ accounts of deceased canons, and in particular Jacques de Houchin, remarkable for his bibliophilic sophistication and (apparently) private music-making. Houchin’s book collection at death ran to more than 300 volumes, including large numbers of classical texts, making him one of the most significant private bibliophiles of his age. He also possessed a large number of music books and musical instruments. Centred on this one man’s proclivities, the chapter paints a picture of private music-making within the confines of the church and its cloister, involving canons, vicars and choirboys.
