Saint Tarsilla was one of the aunts of Gregory the Great. She is one of the venerated virgin saints of the sixth century.
Saint Tarsilla came from a noble family in ancient Rome. Her brother, Gordian, was a senator and was a very rich patrician. Saint Tarsilla and her two other sisters devoted themselves to a religious life and led a life of virginity, fasting, and prayer. They practiced their faith in their father’s house, located on the Clivus Scauri in Rome. Although one of the sisters later abandoned this calling and is thus not venerated as a saint.
Tradition states that Felix III, an ancestor, appeared to Trasilla and bade her to enter Heaven, and on the eve of Christmas Trasilla died, seeing Jesus Christ beckoning.The legend also states that Trasilla a few days later appeared to Emiliana, inviting her to celebrate Epiphany in heaven.
