Adrian of Nicomedia was a military officer and imperial guard serving Emperor Galerius in the late 3rd century. While guarding a court proceeding involving the torture of twenty-two Christians in Nicomedia, he was moved by their courage and declared his own faith. This decision led to his imprisonment and subsequent martyrdom. He died in 306 after suffering severe physical torment, supported by his wife, Natalia. His life and death are often celebrated alongside his wife as a symbol of devoted Christian love.
