The nature of the torture varies with each telling, and can include iron hooks, grilling by fire, placement in a furnace, torture on the wheel, assault by snakes, assailment by arrows, and other assorted methods which she survives. After her father's death, his successor, Dion, continued to torture her. Christina is eventually beheaded. Some scholars have concluded that her legend is the result of pious fiction being mistaken for history. The theme of her legend (a beautiful Christian maiden is tortured to death by pagan men, who in return suffer the wrath of God) is repeated in many ancient and medieval hagiographies, particularly that of Saint Barbara. The entry for her in the 2004 "Roman Martyrology" is very brief: "At Bolsena in Tuscany, Saint Christina, Virgin and Martyr". She was once included in the General Roman Calendar. The Tridentine Calendar gave her a commemoration within the Mass of the Vigil of Saint James. When in 1955 Pope Pius XII suppressed this vigil, the celebration of Saint Christina became a "simple" and in 1960 a "commemoration". The 1969 revision omitted her from that calendar, "because nothing is known of this virgin and martyr apart from her name and her burial at Bolsena", but not from the Martyrology, the official list of recognized saints. According to the present rules in the Roman Missal, Saint Christina may be celebrated with a "memorial" everywhere on her feast day, unless in some locality an obligatory celebration is assigned to that day. Toffia in the Province of Rieti displays her relics in a transparent urn. Palermo, of which Christina is one of four patron saints, also claims to hold her relics. The Eastern tradition that connects Christina with Tyre, Lebanon may be due to confusion with the name of a locality near Bolsena. Contrary to local belief, Christina of Bolsena is not the saint whose remains are interred in The Cathedral of St. John the Evangelist in Cleveland, Ohio. A second legend is connected to Christina. The Eucharistic miracle, depicted in Raphael's The Mass at Bolsena, is often considered to be the catalyst for the Feast of Corpus Christi, recalls an event in the Umbrian region of Italy in 1263. A priest named Peter from the city of Prague nurtured doubts regarding the transubstantiation of the Host during Mass, and during his pilgrimage toward Rome prayed to be relieved of his questions. While saying the words of consecration in the Basilica of Santa Cristina at Bolsena, the Host dripped blood on his hands and on the cloth below.
