Nicasius of Rheims was a 4th or 5th-century bishop of Reims who lived during the era of Ancient Rome. He is primarily remembered for establishing the original Reims Cathedral and for his courageous stance during the barbarian invasions. According to tradition, he met a violent end at the hands of invaders, either the Vandals or the Huns, while attempting to protect his people. Because he reportedly survived a bout of smallpox, he is venerated as a patron saint for those suffering from the disease.
Life and death


As the archbishop of Reims, Nicasius is credited with prophesying the arrival of invaders. He encouraged his followers to rely on divine mercy rather than combat. During the siege, he sought to delay the barbarians to allow citizens to flee, resulting in his martyrdom. Some accounts describe him as a cephalophore, a saint who continues to recite psalms after being decapitated. He was killed alongside his sister, a deacon, and a lector.
Veneration and legacy


Nicasius is honored as the patron saint of people afflicted by smallpox. His legacy includes a Benedictine abbey in Reims named in his memory. He is commemorated in the Catholic and Orthodox traditions, with his feast day observed on 14 December. Artistic depictions often show him holding his own head, reflecting the stories of his martyrdom.
