Today, were it not a Sunday this year, would be the feast of St Christina of Bolsena.
Phyllis Jestice posted about her cult on the Medieval Religion discussion group in 2004 and 2008 as follows:
Christina of Bolsena (3rd cent.) The Roman Christina converted to Christianity while still a girl throught the influence of her grandmother. Legend says that she then went around her parents' house destroying all the cult images, and when her father reacted by throwing her into Lake Bolsena with a rock tied around her neck she was miraculously saved from drowning. She then---legend goes on to report---had her tongue cut out and survived five days in a furnace, after which she was finally killed with arrows.
Christina of Tyre (?) This Christina's legend seems to be mixed up with that of Christina of Bolsena. She was a young girl, imprisoned for her Christianity, tortured extravagantly---a fire was lit under her but got out of control and burned 100s of people to death; her breasts were cut off and milk flowed from them; her tongue was cut out but she spoke even more clearly than before and when she threw her tongue at the judge he lost the sight of an eye; best of all, when she was thrown into the sea she was baptized by Christ and returned to land by the archangel Michael.

This year John Dillon has posted the following piece on the Medieval Religion discussion group:
Christina (variously called "of Tyre" or "of Bolsena") is a martyr of the Via Cassia venerated at today's Bolsena (VT) in the Tuscia section of Lazio in what was once southern Etruria. Her cult there is attested archeologically from the later fourth century onward and a saint of her name appears among the overwhelmingly Western virgin martyrs in the restored later sixth-century mosaics (ca. 560) in the nave of the basilica di Sant'Apollinare Nuovo in Ravenna.
Christina has similar, legendary Passiones both in Greek and in Latin (BHG 301, 302; BHL 1749-1759); their narrative core is thought to be an expansion of Eusebius of Caesarea's account of the Theodosia of his De martyribus Palaestinae. The Greek ones, whose oldest known representative is a papyrus fragment of the fifth or early sixth century, make her a martyr of Tyre in Phoenicia, as do also her entry in the (pseudo-)Hieronymian Martyrology and her earlier Latin Passiones. Apart from these texts there's no ancient indication of Christina's having had a cult at Tyre. The earlier Passiones present her as a young virgin of Christian faith who refuses to sacrifice to idols set before her by her pagan father (a high public official) and who then undergoes a series of ineffective tortures before being slain by the sword.
The ninth-century martyrologies of St. Ado of Vienne and Usuard of Saint-Germain place Christina's martyrdom at Tyre, a city of Italy; Ado specifies that this is situated at the Lake of Bolsena. Christina's later Latin Passiones also specify an Italian locale. These convert an episode in which in earlier texts she is thrown into the sea with a millstone tied to her neck (she survives and is baptized by Christ) into one in which she is instead cast into the Lake of Bolsena. After various torments she is shot to death with arrows. How her earlier dossier came to specify Tyre is a mystery; possibly an adjective _Tyrrhena_ ("Etruscan") in a now lost early Passio got corrupted into something that was copied as _Tyria_ ("Tyrian").
A literarily noteworthy Latin Passio of Christina is that by Alfanus of Salerno (BHL 1759; eleventh-century). Aldhelm has a much briefer version in his prose De laude virginitatis. Sherry Reames' introduction to her TEAMS edition of William Paris' late fourteenth-century Life of St Christina is here:
And her text of that Life is here:
Christina's cult site at Bolsena's basilica di Santa Cristina developed from a late antique martyrium in a subterranean Christian necropolis into the eleventh- and twelfth-century hypogean basilica shown here and called the Grotta di Santa Cristina:
Early medieval pilgrim itineraries and historical notices attest to the fame of this spot. Before the apse is Christina's rather grand late antique tomb. When it was opened in 1880 it was found to contain a fourth(?)-century funerary urn of marble bearing the tenth- or eleventh-century inscription †I·RQES/CP·BAT·X·M
i.e. †HIC REQUIESCIT CORPUS BEATAE CHRISTINAE MARTYRIS
Human bones said to have come from someone not above fourteen years of age were found in the urn and are now kept in a new, silver urn in a chapel in the upper church. In the eleventh and twelfth centuries other relics said to be Christina's were translated to various places in Christendom.
A view of the adjacent fourth- and fifth-century catacomb:
Just outside the Grotta are an altar and ciborium from the Carolingian period. Bolsena's Eucharistic Miracle of 1263 or 1264 is said to have occurred here:
The altar incorporates a piece of basalt said to have been used to weigh down the saint when she was thrown into the lake and piously believed to bear the imprint of her feet:
Christina is entered under today in the (pseudo-)Hieronymian Martyrology, in the ninth-century martyrologies of St. Ado of Vienne and Usuard of Saint-Germain, and in the originally tenth-century Synaxary of Constantinople. Today (24. July) is her feast day in Byzantine-rite churches and her day of commemoration in the Roman Martyrology.

Back in 2008 another contributor to the group posted about the annual pageant of S. Cristina in Bolsena, which I assume originated as a medieval mystery play, as follows:
"At Bolsena Cristina's Passio is re-enacted annually (with hunky male torturers; in the developed legend she's said to have possessed great physical beauty). Views of one such pageant are at the foot of this page:
And here are others:
Now that really is a case of "Well, we don't do that at our church " and indeed might make even the most fervent supporters of reviving traditional paraliturgical practices think twice. Or perhaps not.
