Christian Feast Day: Adrian and Natalia of Nicomedia (Roman Catholic Church)

Adrian of Nicomedia or Saint Adrian was a Herculian Guard of the Roman Emperor Galerius. After becoming a convert to Christianity with his wife Natalia (Ναταλία), Adrian was martyred at Nicomedia in Asia-Minor (Turkey). Adrian was the chief military saint of Northern Europe for many ages, second only to Saint George, and is much revered in Flanders, Germany and the north of France.
