Quirinus of Neuss was a Roman tribune during the 2nd century who is honored as a saint. Born in Rome around 100, he reportedly converted to Christianity after observing various miracles. Following his conversion, he faced severe persecution, suffering mutilation to his tongue, hands, and feet. He was eventually executed by decapitation in 116. His death in Rome led to his burial in the Catacomb of Prætextatus, though he is most closely associated with the city of Neuss.
