St. Aquilinus of Milan (d. 1015 A.D.), also known as St. Aquilinus of Cologne, was born to a noble family in Bavaria, Germany. He received his education in Cologne, Germany and was ordained to the priesthood. He was offered the bishopric of Cologne, but turned it down in order to be a missionary priest and itinerant preacher. He traveled through various European cities fighting against the dangerous and spreading heresies of the Cathars, Manichaeans, and Arians. He was also known to work miracles by healing people from disease, especially during a cholera epidemic. He eventually settled in Milan, Italy, and was so effective in his preaching against the Arian heretics that they stabbed him to death and threw his body in the city sewer. His body was recovered and buried in the Basilica of San Lorenzo, in a chapel which now bears his name. His feast day is January 29.
