Before we proceed to the process and the methods of invention, it is not superfluous to advert to a question which has often been made, and by some has been answered in the negative; _whether it be within the artist's province or not, to find or to combine a subject from himself, without having recourse to tradition or the stores of history and poetry_? Why not, if the subject be within the limits of art and the combinations of nature, though it should have escaped observation? Shall the immediate avenues of the mind, open to all its observers, from the poet to the novelist, be shut only to the artist? shall he be reduced to receive as alms from them what he has a right to share as common property? Assertions like these, say in other words, that the Laocoon owes the impression he makes on us to his name alone, and that if tradition had not told a story and Pliny fixed it to that work, the artist's conception of a father with his sons, surprised and entangled by two serpents within the recesses of a cavern or lonesome dell, was inadmissible and transgressed the laws of invention. I am much mistaken, if, so far from losing its power over us with its traditional sanction, it would not rouse our sympathy more forcibly, and press the subject closer to our breast, were it considered only as the representation of an incident common to humanity. The ancients were so convinced of their right to this disputed prerogative that they assigned it its own class, and Theon the Samian is mentioned by Quintilian, whom none will accuse or suspect of confounding the limits of the arts, in his list of primary painters, as owing his celebrity to that intuition into the sudden movements of nature, which the Greeks called φαντασιας, the Romans _visiones_, and we might circumscribe by the phrase of 'unpremeditated conceptions' the re-production of associated ideas; he explains what he understood by it in the following passage adapted to his own profession, rhetoric.[70] 'We give,' says he, 'the name of visions to what the Greeks call phantasies; that power by which the images of absent things are represented by the mind with the energy of objects moving before our eyes: he who conceives these rightly will be a master of passions; his is that well-tempered fancy which can imagine things, voices, acts, as they really exist, a power perhaps in a great measure dependent on our will. For if these images so pursue us when our minds are in a state of rest, or fondly fed by hope, or in a kind of waking dream, that we seem to travel, to sail, to fight, to harangue in public, or to dispose of riches we possess not, and all this with an air of reality, why should we not turn to use this vice of the mind?--Suppose I am to plead the case of a murdered man, why should not every supposable circumstance of the act float before my eyes? Shall I not see the murderer unawares rush in upon him? in vain he tries to escape--see how pale he turns--hear
