On stating to Valerian the urban prefect that she was a Christian, she was beaten to death, and her body was thrown into the sewer.
Irenaeus found the body of St. Concordia and with the help of his colleague Abundius, was able to retrieve it and deliver it to Justinus, who reverently buried her on 25 August in the cemetery of Hippolytus on the Ager Veranus.
Her death, however, is commemorated on 22 February in the Martyrologium Hieronymianum, with a clear indication that she was buried in the cemetery of St. Laurence on the Via Tiburtina.
[2] As a result of this activity, Irenaeus and Abundius after being reported to the prefect, were thrown into the sewer and suffocated by the orders of Valerian, on 26 August.
A basilica was erected in their honor near San Lorenzo fuori le Mura.
