What is "geminianus"

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.

Nothing more is directly known about him, and all the information we have about him comes from much later biographies. It is said that when Saint Athanasius was entering exile in France, he passed through Modena and was received kindly by Geminianus. Saint John Chrysostom later received the same hospitality. Saint Geminianus opposed Arianism and Jovinianism. He probably died on 31 January 397.
