Chromatius was a Roman prefect who had condemned Christians to death. According to legend, Chromatius was converted by St. Tranquillinus and baptized by Polycarp. Chromatius' only son, Tiburtius, was baptized as the godchild of St. Sebastian. Tiburtius was martyred under Diocletian in 286. Today he is commemorated on the traditional calendar together with St. Susanna, Virgin, Martyr.
