Nicodemus of Mammola was a 10th-century monk who lived in the Calabria region of Italy. Born around 900 in the area of Cirò, he sought a life of asceticism among the monks of the Pollino mountains. Although initially rejected by the abbot Fantinus due to concerns regarding his ability to endure strict penance, he eventually joined the community. He later founded a monastic presence on Mount Cellerano before moving his followers to Gerace and finally to Mammola to escape raids.
