Chelidonia was a Benedictine hermitess born in Cicolano, Italy, in 1077. She spent much of her life living as a recluse within a cave, known today as Marra Ferogna, located in the mountains near Subiaco. After choosing this solitary path, she received her religious habit from Cardinal Cuno of Frascati. She died in Subiaco in 1152 and is recognized as a saint within the Catholic Church.
