Who they were
Denis, a Christian of Rome of Gaulish origin, was among the seven bishops sent to Gaul in the third century and was given Lutetia, today's Paris. Around 250 he was martyred with the priest Eleutherius and the deacon Rusticus, a sign that the Church there was already organised.
The life of St Genevieve, written in 520, speaks of the basilica she built where he died, which grew into the great abbey of Saint-Denis; the hill took the name Montmartre, 'mount of the martyrs'. He was at times confused with Dionysius the Areopagite converted by St Paul in Athens.
The miracles
There was never a formal cause: Denis has been honoured as a martyr since the early centuries. He is regarded as the founder of the Church of Paris and of France.
Why that counted as sanctity
Denis brought the Gospel to Paris and sealed it with his blood together with his priest and deacon.
