Juliana Falconieri was a 14th-century Italian nun from a noble Florentine family. Influenced by her uncle, a founder of the Servite Order, she dedicated herself to a consecrated life and joined the Third Order of Servites around 1285. She eventually established the first convent for the Mantellate Sisters, a community focused on serving the sick. Serving as the community's superior for thirty-five years, she remained a devoted leader until her death in Florence in 1341.
