About Bartolo Longo
Bartolo Longo (1841–1926) was an Italian lawyer whose life took a dramatic turn from Satanism to profound Catholic faith and devotion. He became a Dominican tertiary, dedicating himself to the propagation of the Rosary and the veneration of the Virgin Mary. His significant contributions include the founding of the Shrine of Our Lady of Pompei and extensive charitable works, leading to his eventual canonization.
Life and historical context
Born in Latiano on February 10, 1841, Bartolo Longo came from a prosperous family. He pursued law at the University of Naples, a period marked by the rise of Italian nationalism and the growing popularity of spiritualism. Influenced by these currents, Longo reportedly became a Satanic priest. However, a period of intense spiritual struggle and illness led him to seek spiritual guidance from Dominican friar Alberto Radente and religious sister Caterina Volpicelli. They introduced him to devotion to the Virgin Mary and the Rosary, aiding his conversion back to Catholicism.
On October 7, 1871, Longo embraced the Dominican tertiary life, taking the name Rosario. He also engaged in charitable work with Franciscan friars, assisting the poor and the ill. His legal practice brought him to Pompei, where he was struck by the erosion of faith and prevalence of superstition among the populace. Inspired by a promise of the Blessed Virgin to Saint Dominic, Longo committed himself to promoting the Rosary as a means of spiritual renewal.
Major contributions
Longo's most enduring legacy is the Shrine of Our Lady of Pompei. With the support of Countess Mariana di Fusco, he initiated the restoration of a dilapidated church and established a confraternity of the Rosary. In 1875, he acquired a painting of Our Lady of the Rosary, which he had restored and placed in the church. As alleged miracles began to be reported, the church grew in popularity, leading to its expansion and eventual consecration as a basilica. Longo also authored spiritual works, including "The History of the Sanctuary of Pompei."
He and Countess di Fusco married in 1885, entering into a Josephite marriage, and jointly organized significant charitable initiatives, such as schools and homes for orphans. In 1906, they donated the Shrine of Our Lady of Pompei to the Holy See.
Legacy
Bartolo Longo's dedication to peace and social welfare was recognized with nominations for the Nobel Peace Prize in 1902 and 1903. His cause for sainthood progressed after his death, with his spiritual writings approved by theologians. He was beatified by Pope John Paul II on October 26, 1980, who referred to him as the "Apostle of the Rosary." His canonization was officially proclaimed by Pope Leo XIV on October 19, 2025, solidifying his place as a significant figure in Catholic devotion and social action.
