Georges Rouget in the context of "Leonidas at Thermopylae"

Leonidas at Thermopylae is an oil-on-canvas painting by French artist Jacques-Louis David. The work currently hangs in the Louvre in Paris, France. David completed the massive work (3.95 m × 5.31 m) 15 years after he began, working on it from 1799 to 1803 and again in 1813–1814. Leonidas at Thermopylae was purchased, along with The Intervention of the Sabine Women, in November 1819 for 100,000 francs by Louis XVIII, the king of France. The piece depicts the Spartan king Leonidas prior to the Battle of Thermopylae. David's pupil Georges Rouget collaborated on it.
