Although he became a satanist as a young man, Bartolo Longo later became a fervent promoter of the Rosary and founded a major shrine to Our Lady in Pompeii.
On October 19, 2025, Pope Leo XIV will preside over the canonization Mass for seven saints at the Vatican. Among them is the Italian Bartolo Longo (1841-1926), founder of the Pontifical Shrine of Our Lady of the Rosary of Pompeii, a major center of Marian spirituality much loved by recent popes.
A native of Puglia, Bartolo Longo was raised in a religious environment, but turned away from it violently when he moved to Naples to study law. A reader of Ernest Renan, he then adhered to the positivist movement, which forcefully rejected any supernatural reality. During this period, he frequented occult circles and even went so far as to officiate at satanic masses.
