In 1883, nearly forty years after she completed the fresco of Mater Admirabilis on a corridor wall of the Trinita dei Monti in Rome, Pauline Perdrau painted another study of Mary—one much less famous than her earlier work. Though its aesthetic qualities leave much to be desired, this later Mater, which is known in the United States chiefly through the copy made by Sister M.M. Nealis in 1935, rewards careful study and comparison with the Trinita fresco.
