From Wikipedia, the free encyclopedia. Mater Admirabilis is a fresco depicting the Virgin Mary, at the TrinitÃ  dei Monti, a church in Rome. It was painted by a young French girl, Pauline Perdrau, and has been associated with several miracles. Legend has it Pauline had been asked by the nuns at TrinitÃ  dei Monti to paint a mural of the Blessed Mother.
When the painting was complete, the colors were thought to be too vivid. The fresco was covered with a protective cloth to give the paint time to dry. Days later, when the cloth was removed, the colors had softened to the shades of pink and blue and ivory that are so well known to visitors to Materâs shrine today.
