Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto to you is born this day in the city of David a Savior, which is Christ the Lord.
The above picture is Da Vinci's Madonna of The Rocks or sometimes called The Virgin of the Rocks. The original painting is in the Louvre, while the charcoal sketch hangs in the London National Gallery of Art (our favourite museum bar none), along with a second painting. There is a controversy as to which painting came first, whether Da Vinici's assistants worked on the painting in the National Gallery, and whether Da Vinici was forced to alter the paintings. Wiki has a good article here on the paintings.
