"Le istituzioni di pietà che si esercitano a Roma" by Guglielmo Costanzi
Given that on every streetcorner in Rome, “one may take part in and practice religious works,” in 1825 a clergyman called Guglielmo Costanzi wrote two volumes dedicated to Roman institutions of piety “for the edification of foreign visitors who arrive in the city in a Jubilee year”. He described churches, colleges, hospitals, catacombs and sacred places in terms of the rites, ceremonies, religious works and spiritual exercises performed there, specifically eschewing the intention of “educating antiquarian-focused readers who come to Rome to seek the fine arts, but rather for the devoted who walk the streets of this city to find fodder for their religious spirit”.
