Saint Tiburtius
Christian martyr
About Saint Tiburtius
Lived 100 – 300.
Tiburtius, according to Christian legend, was a Christian martyr and saint. His feast day is 11 August which is the same as Saint Susanna. The two were not related, but are sometimes associated because they are venerated on the same day.
Hagiography The story is related in the legend of Sebastian that Agrestius Chromatius, allegedly prefect of Rome, condemned several Christians to death. The prefect, however, was converted by Tranquillinus, father of Mark and Marcellian, and baptized by Polycarp.
Tiburtius was the only son of Agrestius Chromatius; he was also baptized through the persuasion of Sebastian, who was his godfather in baptism, according to this legend.
Tiburtius lay hidden during the persecution by Roman Emperor Diocletian in his father's house. Accused by a traitor, he was brought before the (allegedly) prefect Fabianus at the third milestone of the Via Labicana in the year 286. The spot of execution was called "at the two laurel trees" (ad duas lauros). The commemoration of him that was included in the General Roman Calendar was removed in 1969, because "apart from his name, the only thing known of him is that he was buried in the Inter duas lauros cemetery on the Via Labicana on an 11 August".
