Erasmus of Formia (died c 303) Christian marytr and saint

There are two Christians called Erasmus in the history of Christianity

Saint Elmo is venerated as the patron saint of sailors and abdominal pain. He is one of the Fourteen Holy Helpers.

He was Bishop of Formia, Italy, during the persecution of Christians by emperors
Diocletian and Maximian Hercules. He went to Mount Libabus where he hid for 7 years. An angel counseled him to return to the city.

The Acts of Saint Elmo compiled from Legends tell us that
on his way back to the city he met some soldiers who questioned him. He admitted to being a Christian. He faced Diocletian. He was bound with chains and thrown into prison- an angel helped him escape.

He continued to confess his faith and Maximian had him enclosed in a barrel with protruding spikes and rolled down the hill - an angel intervened.
He must eventually have died a cruel martyr’s death

A number of unreliable legends fill Erasmus’ story.
