The mountain of Sainte-Victoire, a distinctive landmark near Aix-en-Provence, was one of Cézanne's favourite subjects. He never tired of exploring its structure and changing appearance. This picture was painted in the early 1890s from a position to the south-west of Aix overlooking the valley of the River Arc. Its unfinished state provides some insight into Cézanne's working method and his 'constructive' brushwork. Foreground foliage, undulating fields, the distant mountain and sky have emerged gradually from a harmonious patchwork of colours applied across the canvas.
