Magnus of Cuneo was a martyr associated with the legendary Theban Legion, a military group commanded by Maurice. According to local tradition, he fled to the mountains of Piedmont after the legion's decimation at Agaunum in 286 AD to preach Christianity in the Alps. Although historical or archaeological evidence for this connection is lacking, he is remembered as a soldier who was eventually martyred in the region. He is commemorated as a saint in the Catholic Church on August 19.
