Alferius was a 10th and 11th-century Italian Benedictine abbot and bishop born into the noble Pappacarbone family of Salerno. After serving the Prince of Salerno, he traveled to France, where an illness led him to vow monastic life upon his recovery. Following a period at Cluny, he eventually settled near Monte Finestra to pursue a life of prayer. He became the founder of the monastery of La Trinità della Cava, which was established under the Benedictine rule.
Life and foundation

After his time in France, Alferius lived as a hermit near Cava. His reputation for holiness attracted a group of monks who wished to join his contemplative community. In 1011, he formally established the monastery of La Trinità della Cava. He served as the leader of this religious community, which grew from a small group of hermits into a significant Benedictine institution.
Veneration
Alferius is recognized as a saint within the Catholic tradition. In 1893, Pope Leo XIII officially recognized him as one of the first four abbots of Cava to be considered saints. His feast day is observed annually on April 12, marking the anniversary of his death at the Territorial Abbey of La Trinità della Cava.
