Maria Adeodata Pisani was a 19th-century Benedictine nun and abbess born in Naples. After her family moved to Malta following her father's political exile, she chose a contemplative life over marriage, entering the cloistered St Peter's Monastery in Mdina. Known for her mysticism and devotion to the poor, she served the community in various roles, including sacristan and teacher. She was beatified by Pope John Paul II in 2001, who recognized her spiritual maturity and dedication to her religious vows.
