Symphorian (Symphorianus, Symphorien), Timotheus (Timothy), and Hippolytus of Rome are three Christian martyrs who though they were unrelated and were killed in different places and at different times, shared a common feast day in the General Roman Calendar from at least the 1568 Tridentine Calendar to the Mysterii Paschalis. While still a young man, Symphorian was either beheaded or beaten to death with clubs.
