Magnus of Trani was a third-century bishop and martyr whose historical identity remains a subject of scholarly debate. Known also as Magnus of Anagni, he lived in Italy and is associated with various hagiographic traditions. While some researchers suggest he may have been a Lombard bishop, others view him as a paleo-Christian martyr from the Lazio region. His legacy is deeply tied to the city of Anagni, where he is honored as a patron saint alongside his apprentice, Saint Secundina.
