Well, I have spoken at length of Rembrandt, because his way of idealising a scene through the beauty and mystery of light, has become the way of modern artists. But it was not until nearly two hundred years after his death that the world came round to this way. In the mean time Rembrandt and the other Dutch painters of his Century, like Velasquez, had been forgotten. The painters were busy trying to keep alive the other notion of idealism, the Italian one, based on form. Indeed, it was not until naturalism again became popular, that idealism by means of light was renewed.
