There has been much unnecessary ingenuity exercised on the question, whether the ancients studied anatomy. Undoubtedly they did not study it in our fashion, yet that they possessed all the knowledge of it which art requires, can not be denied. The finer specimens of ancient statuary evince a more perfect acquaintance with anatomy, as far as it is shown in the proportions, general forms, and action of the body, than the productions of those modern sculptors and painters who have pursued this art with the greatest zeal and success--even than Michael Angelo himself. As we have seen in the works of the masters, let the young artist avoid exhibiting the anatomy or displaying his knowledge, else he will fall into the caricature of Fuseli instead of attaining the vigor of Buonarotti. Anatomy is not to be displayed, but its true use is to beget an accurate observation of nature in those slighter characteristics which escape a less learned eye.
