Geminianus was a fourth-century deacon who eventually served as the second Bishop of Modena. Born in Modena around 312, he is historically noted for attending a council in Milan around 390, which was convened by Saint Ambrose. His name suggests he may have originated from a family of Roman senators. Throughout his ministry, he actively opposed the heresies of Arianism and Jovinianism, and he is remembered for providing hospitality to figures such as Saint Athanasius and Saint John Chrysostom.
Life and work

During his leadership in Modena, Geminianus was known for his religious convictions. He provided refuge to Saint Athanasius during his exile in Gaul and later hosted Saint John Chrysostom. His historical presence is confirmed by his participation in the Milanese council. He likely passed away in early 397, with his death traditionally observed on January 31.
Veneration and legacy

The saint has been honored in Modena since at least the fifth century, when a church was built near his tomb. In the Middle Ages, the city was sometimes referred to as Civitas Geminiana. He is also venerated in Tuscany, particularly in San Gimignano and Pontremoli. Artistic depictions often show him as a bishop holding a model of Modena or performing miracles, such as calming storms.
