"Napoleon Across the Pass of St. Bernard in the Alps" is the collective name of five oil paintings painted by Jacques-Louis David. They painted the scene when Napoleon Bonaparte crossed the St. Bernard Pass before launching the Battle of Marengo. The client was not Napoleon, but the Spanish King Carlos IV. The works were successively completed between 1801 and 1805, two of which are hidden in the Palace of Versailles, and the remaining three are hidden in the Belvedere Palace in Vienna, Charlottenburg Palace in Berlin and Rueil Malmaison Castle. The scene in the painting does not completely correspond to reality, because in fact Napoleon was riding a donkey instead of a horse, and the weather at that time was not bad. Some experts explained that it may be that donkeys have stronger endurance and horses are more suitable for charging. Therefore, it was not that Napoleon had no strength, it should be the needs of the situation at the time. The author painted the donkey as a horse, perhaps because he wanted to show Napoleon's mighty and tall image.
