Gautier de Coincy (1177–1236) was a French abbot, poet and musical arranger, chiefly known for his devotion to the Virgin Mary.
While he served as prior of Vic-sur-Aisne he compiled Les Miracles de Nostre-Dame (known in English as The Miracles of Notre Dame or The Miracles of Our Lady) in which he set poems in praise of the Virgin Mary to popular melodies and songs of his day. It is a reverential but humorous work, full of love for the cult of the Virgin Mary, which at that time also received attention from Saint Bernard of Clairvaux who was the leading medieval proponent of veneration of the Virgin as a counterbalance to the more rigorous Christian scholasticism, then the dominating spiritual force.
Unlike Clairvaux's more sombre tomes, de Coincy's book (whilst sharing much of the same ideological bedrock) tends more towards the indulgent or soft-hearted. Many of the songs de Coincy wrote were set to popular ballads then in vogue at the royal court, or borrowed the tune of pastoral or romantic ditties. The Miracles of Our Lady is one of the most popular works of Marianist literature from the period and it encapsulates a very particular set of Christian values, which saw in the Virgin Mary the most benevolent and humanistic aspect of salvation, intercession and mercy. Many of the songs are concerned with the key elements of the Virgin's earthly life - her conception, her birth, her childhood, her youth in the Temple, the events recorded in the Biblical gospels and her Dormition; the poems and stories are generally more concerned with her modern-day miracles.
