Thorwaldsen's life lasted from 1770 to 1844, and was very industrious. He was the son of a Copenhagen ship-carver, and received all his bent from the study of the antique in Italy. The works he left are almost innumerable, and some of them will have lasting reputation. The finest perhaps is his medallion of Night, "launched with infinite lightness into space, carrying in her arms her two children, Sleep and Death." This masterpiece is said to have been conceived during a sleepless night in 1815, and modeled in one day. His Lion at Lucerne, made to commemorate the Swiss guards at Paris who fell in defending the Tuileries, August 10, 1792, is known to every tourist: it is altogether conventional, but it is not commonplace. "Never having seen a live lion," says his biographer, "he went to antique statues for inspiration:" he thus, at two or three removes from Nature, secured a grand, monumental conception, fully charged with human intelligence. The colossi of Christ and his Twelve, now to be seen with the artist's other works at Copenhagen, and formerly exhibited at the World's Fair in New York, are imposing and classical, while they perhaps show the absence of the Christian idea noted in his other clerical subjects. Thorvaldsen, born a Lutheran, was a spectator in Rome of bigotry and skepticism, and took refuge in artistic impartiality. A friend once observing that his want of religious faith must make it difficult to express Christian ideas in his works, "If I were altogether an unbeliever," he replied, "why should that give me any trouble? Have I not represented pagan divinities?--still, I don't believe in them." The life of this artist was one of consummate worldly success; the kings of Bavaria and Denmark were the personal friends of the unlettered son of the ship-carver, as were Horace Vernet, Walter Scott, Andersen, and Mendelssohn; his casket of decorations was the amusement of his lady visitors; and his invitations were so constant that he could not always remember the name of his host: he was at once parsimonious and charitable, cheerful and melancholy. His artistic influence was very strong, exhibiting itself in the style of Tenerani, Galli, Rauch, Drake and Bissen. The life of him by Plon is methodical and complete, and the American version is illustrated by thirty-five careful engravings printed in Paris and gummed upon the sheets. Expiation.
