Saint Geminianus (also known as Saint Geminian, or Saint Gimignano) was a fourth century Deacon, and later Bishop of Modena. He is mentioned in the year 390 when he sent a delegate named Aper to participate in a council called by Saint Ambrose in Milan. From his name, it has been deduced that Geminianus probably belonged to the caste of Roman senators.
