Note 310 — Chapter VII · MUSIC AND PLASTIC
Charles Francis Atkinson translation
In Classical painting, light and shadow were first consistently employed by Zeuxis, but only for the shading of the thing itself, for the purpose of freeing the modelling of the body painted from the restriction of the relief-manner, i.e., without any reference to the relation of shadows to the time of day. But even with the earliest of the Netherlanders light and shade are already colour-tones and affected by atmosphere.
