Although it is universally admitted that the Greeks carried sculpture and architecture to such a state of perfection that they have never been equalled by the moderns, except in imitating them, yet there is a great contrariety of opinion among the most eminent modern writers as to their success in painting; some, full of admiration for the works of antiquity which have descended to us, have not hesitated to declare that the Greeks must have been equally successful in painting, while others, professing that we possess colors, vehicles, and science (as the knowledge of foreshortening, perspective, and of the chiaro-scuro) unknown to them, have as roundly asserted that they were far inferior to the moderns in this branch, and that their pictures, could we now see them in all their beauty, would excite our contempt. Much of this boasted modern knowledge is, however, entirely gratuitous; the Greeks certainly well understood foreshortening and perspective, as we have abundance of evidence in their works, to say nothing of these being expressly mentioned by Pliny, and that it is impossible to execute any work of excellence without them. This erroneous opinion has sprung from the ignorance and imperfections of _the old fathers_ of Italian art in these particulars, and the discoveries and perfections of those more modern. If the moderns possess any advantages over the ancients, it is that chemistry has invented some beautiful colors unknown to them, the invention of oil painting, and that illusion which results from a perfect acquaintance with the principles of the chiaro-scuro; but even here the mineral colors--the most valuable and permanent--were well known to them; and if they had not oil colors, they had a method of _encaustic painting_ not positively known to us, which might have answered as good a purpose--nor are we sure they did not practice the chiaro-scuro. Besides, the most renowned modern masters were more celebrated in fresco than in oil painting, and the ancients well understood painting in fresco. In this, as in most other disputes, it may reasonably be presumed, that a just estimation of both will be found between the extremes. In comparing the paintings of the moderns with those of the ancients, it may be fairly inferred that the latter surpassed the former in expression, in purity of design, in attitude of the figures, and in ideal beauty. The moderns have doubtless surpassed the ancients in the arrangement of their groups, in perspective, foreshortening and chiaro-scuro--and in coloring.
