Julian of Brioude was a Roman military officer born in Vienne around 300. After fleeing Vienne alongside Ferréol, he eventually met his death in the Auvergne region. He was executed by decapitation in 304, becoming a martyr for his faith. His remains were interred in Brioude, though his head was transported back to Vienne. He is recognized as a saint within the Catholic and Orthodox traditions, with his commemoration occurring annually on August 28.
