© National Geographic Society 14 + Work Restoring the Vatican's Art Treasures Helped Give Brurnidi the Classic Touch Jewel-bright frescoed medallions at the top of these two pages embellish the ceiling of the President's Room. Legislation holds the sword of justice; Liberty draws the ax from the fasces symbolizing power. Brumidi executed the paintings in true fresco. By this method the artist paints moist plaster with pigment mixed with water. When the mortar hardens, colors grow lighter and more brilliant. Air's chemical action on the lime produces a durable finish approaching that of marble. Michelangelo used this technique in decorating the Vatican's Sistine Chapel.
