How this particular picture is helped by a contrast, not of the old fashioned dark and light, as in the _Descent from the Cross_ but of values of color, you can see for yourself, even from the reproduction. Still more would you realize it could you see the freshness and purity and gladsomeness of the original. Contrasts are needful in the composition of a work of art--they are one of the sources of its beauty. But imagine if you can, having shadows and darkness brought into contrast with this white robed figure! How they would contradict the expression of its exquisite purity and loveliness! As it is, the contrast of lower values does not in the least jar upon the expression; on the contrary, it gives it a greater meaning, since it suggests the atmosphere of happiness and brightness that has helped to color the beauty of the girl’s spirit.
