Casts Quote by Leonardo da Vinci
“The light for drawing from nature should come from the North in order that it may not vary. And if you have it from the South, keep the window screened with cloth, so that with the sun shining the whole day the light may not vary. The height of the light so arranged as that every object shall cast a shadow on the ground of the same length as itself.”
