This is one kind of artistic imagination, this which I have rudely symbolised in the symbol of the three carved roses--the imagination which delights the mind by holding before it some charming or uncommon object, and conjuring up therewith a whole train of feeling and fancy; the school, we might call it, of intellectual decoration, of arabesques formed not of lines and colours, but of associations and suggestions. And to this school of the three carved roses in the Square of Purgatory belong, among others, Angelico, Benozzo, Botticelli, and all those Venetians who painted piping shepherds, and ruralising magnificent ladies absorbed in day-dreams. But besides this kind of imagination in art, there is another and totally different. It is the imagination of how an event would have looked; the power of understanding and showing how an action would have taken place, and how that action would have affected the bystanders; a sort of second-sight, occasionally rising to the point of revealing, not merely the material aspect of things and people, but the emotional value of the event in the eyes of the painter. Thus, for instance, Tintoret concentrated a beam of sunlight into the figure of Christ before Pilate, not because he supposed Christ to have stood in that sunlight, but because the white figure, shining yet ghost-like, seemed to him, perhaps unconsciously, to indicate the position of the betrayed Saviour among the indifference and wickedness of the world. Hence I would divide all imaginative art, particularly that of the old Italian masters, into art which stirs our own associations, and suggests to us trains of thought and feeling perhaps unknown to the artist, and art which exhibits a scene or event foreign to ourselves, and placed before us with a deliberate intention. Both are categories of imaginative activity due to inborn peculiarities of character; but one of them, namely, the suggestive, is probably spontaneous, and quite unintentional, hence never asked for by the public, nor sought after by the artist; while the other, self-conscious and intentional, is therefore constantly sought after by the artist, and bargained for by the public. I shall begin with the latter, because it is the recognised commodity: artistic imagination, as bought and sold in the market, whether of good quality or bad. II
