If you've been to the Vatican you've probably seen Michelangelo's sculpture "The Pieta". Beautifully executed in white Carrera marble, it depicts the Virgin Mary holding Christ after he was taken down from the cross. This is a mosiac replica of her face. Mosaic "paintings" are big ticket items in the stores around the Vatican. Small pieces of colored Italian glass in a myriad of colors take the place of paint. And they're all meticulously done.
