ABDON and SENNEN (SS.) MM. (July 30) (3rd cent.) Two Persian nobles who, coming to Rome, or rather brought thither as captives by Decius, when returning from his first successful campaign against the Persians, under the Emperor Gordian, devoted themselves to the service of the imprisoned Christians and to the reverent interring of the bodies of the Martyrs. They were themselves thrown to the wild beasts in the Amphitheatre in the persecution decreed by Decius when he became Emperor (A.D. 250). They were long gratefully remembered by the Christians of Rome and are still annually commemorated in the Liturgy of the Church. The details given concerning them in the otherwise doubtful Acts of St. Laurence the Martyr, their contemporary, seem fairly trustworthy.
