Biography

"Saint Erasmus, also called Elmo (died 303?, Formia, Italy; feast day June 2), early Christian bishop, martyr, and one of the patron saints of sailors, who is romantically associated with Saint Elmo’s fire (the glow accompanying the brushlike discharges of atmospheric electricity that appears as a tip of light on the masts of ships during stormy weather) as the visible sign of his guardianship over them. Erasmus is one of the Fourteen Holy Helpers, a group of saints conjointly venerated in medieval Germany.

He is reported to have been bishop of Formia, where he was martyred, probably during the persecution of Christians by the Roman emperor Diocletian. According to Pope Gregory I (reigned 590–604), his relics were kept in the Cathedral of Formia. After the Saracens destroyed Formia in 842, Erasmus’ body was transferred to Gaeta, Italy, where he is honoured as patron saint."
