Romanus of Subiaco was a 5th-century monk and abbot who lived as a hermit in Italy. He is primarily recognized for his significant role in the early life of Saint Benedict of Nursia. By providing Benedict with food, clothing, and shelter in a cave near the Anio river, Romanus offered essential support during the latter's initial years of eremitic life. After his time in Italy, he traveled to Gaul, where he established a small monastic community.
