04 September - Rosalie was born in 1130 into a noble Sicilian family. She was the daughter of Sinibald, Lord of Quisquina and Rosa, relative of Roger II of Sicily, King of Sicily, and descendant of the family of Charlemagne.

She was a very pious girl, who retired at the age of 14 to a cave on Mount Pellegrino where she spent the last years of her life, drinking water from a spring and feeding on what nature offered her around. In an unknown grotto, wrapped in snow for several months, Rosalie spent a few years, dividing her time between prayer and penance. Often she was visited by the Angels, and the Savior Himself sometimes came to speak with her.

Immediately after her death, her family sent out a search for her throughout Sicily. The angels warned Rosalie that she would soon be discovered if she did not change her home; she immediately took her crucifix and the few objects she had with her and followed her heavenly guides; they led her to Mount Pellegrino, where they showed her a dark and damp cave that served as her retreat for the last eighteen years of her life. She died in 1170.

In 1624 the plague broke out in Palermo. Rosalie first appeared to a sick woman and then to a hunter, to whom she indicated where her relics were. She ordered him to transport her remains to Palermo and to organize a great procession carrying them through the streets of the city. The hunter climbed the mountain and found the saint's remains where she had told him. He did as she had recommended, and at the end of the procession, the plague ceased. After this miracle, St. Rosalie was venerated as the patron saint of Palermo and a shrine was erected in the place where her remains had been found.
