Some of our most successful sculptors have never been abroad, or at least have not systematically placed themselves under the tuition of a foreign master; while a number of them have indicated in their tendencies a natural sympathy with the later movement of modern sculpture, which is rather in the direction of allegory, portraiture, and _genre_ suggested by domestic life. When the ancients represented Venus or Jove in marble, they sculptured a being in whose actual existence they believed, and thus a profound reverence inspired the work of the master. When the sculptor of the Middle Ages carved the deeds of the Saviour, or the saints, or represented the Last Judgment, he was moved by deep love or reverential awe, and an unquestioning belief in the events he was commemorating. But when the sculptor of this century undertakes to revive classical subjects and modes of thought, he encounters an insurmountable obstacle at the outset, which checks all progress, and relegates his art to a secondary rank, without even the benefit of a doubt in his favor. The laws and limitations of mind make it impossible for an art to be of the first order which depends upon the imitation of other art. It is only by copying nature directly, under the inspirations of its own age and country, that a school of art has the slightest chance of immortality. Thorwaldsen, the greatest sculptor since Michael Angelo, exemplified this truth to a remarkable degree. Moved by a realization of classic art which no other modern sculptor except Flaxman has approached, we yet find his classical subjects inferior to those allegorical subjects in which he gave expression to the impulses of his own times. A slowly dawning consciousness that art cannot by any force of will or free agency escape from these limitations of growth is becoming at last evident in recent sculpture, especially in the emotional and sometimes sensational sculpture of France. Lacking repose, it is yet fresh and original, and is destined by continued self-assertion to reach a high rank. It is in imitations of the antique or in allegory, and portraiture, that our sculpture has exerted its best efforts, until within a few years. General Washington has also proved a sort of Jupiter Tonans to our sculptors. Elevated to a semi-apotheosis by the people, he has hitherto been the most prominent subject of the plastic art of the West, and has thus afforded a fair standard of comparison between the merits of different artists, since very few of them but have tried their hand with the national hero. As regards popular appreciation or pecuniary reward, it must be admitted that our sculptors have relatively little cause for complaint.
