Maria Costanza Panas, born Agnese Pacifica Panas,, was an Italian Capuchin Poor Clare. Panas did her education in northern Italian cities before she worked as a teacher. It was not until a short while following her teaching career that she decided to become a nun and so entered a convent in secret after her parents and uncle exhibited opposition to her desire. In the convent she served as novice mistress and served as an abbess on two separate occasions and was even elected to a prominent religious council despite her several severe illnesses during the late 1950s.
