Eusebius of Rome (RM)
Died c. 357. Usuard's ancient martyrology calls this priest who founded a church in Rome (now called titulis Eusebii) a confessor. The spurious acta, say that he was martyred under the Arian Emperor Constantius for having preached against Pope Liberus' signing of the confession of Sirmium. According to these, he was imprisoned for many months and died during confinement (Benedictines, Encyclopedia). In art, Saint Eusebius is portrayed being carried to heaven. The angels hold a chain, a chalice, and the Gospel of John. He may also be shown speaking without a tongue (Roeder).
August 14
St. Eusebius, Priest and Confessor at Rome
HE is named with distinction in the Latin Martyrologies on this day. The ancient genuine Martyrology of Usuard only styles him confessor under the Arian emperor Constantius, and adds, that he was buried in the cemetery of Calixtus. His acts seem of no authority. They are published by Mombritius, and more correctly by Baluze, t. 2. Miscel. p. 141. These relate that, for opposing Pope Liberius for signing the confession of Sirmium, he was persecuted by the emperor, and imprisoned some months in his room, under which confinement he sanctified himself by continual prayer, and happily died. He is called a martyr in several modern Martyrologies.
