Ambrose (c 340-97) is regarded, along with St Jerome, St Augustine and St Gregory the Great, as one of the four leading Doctors of the Church. Yet his early endeavours were directed entirely towards secular success.

He was born in Trier, where his father held sway as prefect of Gaul. On the death of this powerful parent, Ambrose returned with his mother and sister to Rome, where he became a formidable Greek scholar.

He also proved a highly successful advocate, whose talents were rewarded when Emperor Valentinian established him in Milan as governor of Liguria and Aemilia.
