On the north side of the west transept, this window was the first of the five Nincheri windows to be installed in the year 1941. Our Lady with the Child in vibrant colours dominate; both Mother and Child hold a rosary in hand. At their feet are St. Dominic and St. Catherine of Siena, traditional saints of the Rosary. The window was chosen by Canada Post in 1997 for its annual Christmas stamp and a plaque commemorates this fact.

Born in Italy in 1885, Nincheri came to Montreal in 1915. A painter and designer who listed Titian and Raphael as his strongest influences, he obtained work with Henri Perdriau, Quebec’s leading decorator of churches. In the years afterward, he went on to produce stained glass windows and frescoes for more than 100 churches in Canada and United States. Dubbed ‘the church’s greatest artist of religious themes’ by Pope Pius XI, Nincheri was knighted by Italy in 1972. Twenty years later, he was also honoured for his contribution during Montreal’s 350th anniversary celebrations. Ian Hodkinson, historian and professor emeritus of art conservation at Queen’s University, notes that Nincheri painted more and bigger murals than any other Canadian artist and “brought tremendous imagination and details to these depictions”.
