Bertel Thorvaldsen (born Nov. 19, 1770, or Nov. 13, 1768, Copenhagen, Den.—died March 24, 1844, Copenhagen), sculptor, prominent in the Neoclassical period, who was the first internationally acclaimed Danish artist. Prominent in Roman intellectual and artistic circles, he influenced many emerging artists from Europe and the United States. Most of Thorvaldsen’s most characteristic sculptures are reinterpretations of the figures or themes of classical antiquity. The Alexander frieze of 1812 in the Palazzo del Quirinale, Rome, modeled in only three months in anticipation of a visit by Napoleon, is an example of the feverish energy with which he could at times work. Religious sculptures include the colossal series of statues of Christ and the Twelve Apostles (1821–27) in the Vor Frue Kirke in Copenhagen. He also made numerous portrait busts of distinguished contemporaries.
