Cecilia, St. at English => English (The Britannica Concise) Of Explained:
Early Christian martyr and patron saint of music. A noble Roman who had dedicated her virginity to God as a child, she was married against her will to a pagan named Valerian. She told him of her vow, and he promised he would let her keep it if he could see the angel with whom she conversed. After being baptized, Valerian saw Cecilia talking to the angel. Valerian's brother also converted, and both were eventually martyred. Cecilia's good works infuriated the Roman prefect, who ordered her burned at the stake; when the flames did not harm her, she was beheaded.
