Eusignius was a martyred Roman soldier. He began his military career under the emperor Maximian.[1] Under the reign of Constantine he served as general and was witness to emperor's vision of a cross in the sky symbolizing victory. Eusignius retired from the military after 60 years of service.[2]
Eusignius was present at the martyrdom of St. Basiliscus and is said to have seen angels and Jesus Christ who took Basiliscus up to heaven.[3]
He was beheaded by Julian the Apostate in 362 for denouncing paganism.
Eusiginius is one of the 140 Colonnade saints which adorn St. Peter's Square.
