Maria Costanza Panas was an Italian nun of the Capuchin Poor Clare order who lived from 1896 to 1963. Born Agnese Pacifica Panas, she initially pursued a career as a teacher following her education in northern Italy. Despite opposition from her family, she entered a convent in Fabriano in 1917. She eventually rose to leadership roles within her order, serving as both a novice mistress and an abbess on two separate occasions. Throughout her life, she maintained a deep spiritual focus, even dedicating her writings exclusively to Christ.
