in neoclassicism under a self-effacing finish. Sculpture remained largely impervious to Romanticism, probably partly for technical reasons, as the most prestigious material of the day, marble, does not lend itself to expansive gestures. The leading sculptors in Europe, Antonio Canova and Bertel Thorvaldsen, were both based in Rome and firm Neoclassicists, not at all tempted to allow influence from medieval sculpture, which would have been one possible approach to Romantic sculpture. When it did develop, true Romantic sculpture—with the exception of a few artists such as Rudolf Maison— rather oddly was missing in Germany, and mainly found in France, with François Rude, best known from his group of the 1830s from the Arc de Triomphe in Paris, David d'Angers, and Auguste Préault. Préault's plaster relief entitled Slaughter, which represented the horrors of wars with exacerbated passion, caused so much scandal at the 1834 Salon that Préault was banned from this official annual exhibition for nearly twenty years. In Italy, the most important Romantic sculptor was Lorenzo Bartolini. In France, historical painting on idealized medieval and Renaissance themes is known as the style Troubadour, a term with no equivalent for other countries, though the same trends occurred there. Delacroix, Ingres and Richard Parkes Bonington all worked in this style, as did lesser specialists such as Pierre-Henri Révoil (1776–1842) and Fleury-François Richard (1777–1852). Their pictures are often small, and feature intimate private and anecdotal moments, as well as those of high drama. The lives of great artists such as Raphael were commemorated on equal terms with those of rulers, and fictional characters were also depicted. Fleury-Richard's Valentine of Milan weeping for the death of her husband, shown in the Paris Salon of 1802, marked the arrival of the style, which lasted until the mid-century, before being subsumed into the increasingly academic history painting of artists like Paul Delaroche. Another trend was for very large apocalyptic history paintings, often combining extreme natural events, or divine wrath, with human disaster, attempting to outdo The Raft of the Medusa, and now often drawing comparisons with effects from Hollywood. The leading English artist in the style was John Martin, whose tiny figures were dwarfed by enormous earthquakes and storms, and worked his way through the biblical disasters, and those to come in the final days. Other works such as Delacroix's Death of Sardanapalus included larger figures, and these often drew heavily on earlier artists, especially Poussin
