Leonidas at Thermopylae is an oil painting produced in 1814 by French painter Jacques Louis David.
David made many sketches in starting as a trial for his composition and then constantly changing the groups and the poses of the figures. Leonidas was seen in three quarter profile In an early drawing around 1799 and the groups around him were more confusing. In the background of the painting an immense landscape of rocks was closed off. In the final painting, the tree has far fewer branches and leaves on the right because now, we can see a caravan of mules leaving from battlefield. Louis did this to free up the background.
The drawing was produced for a friend of Louis named as Count Sommariva, an art lover. It was purchased by the Louvre in Paris during the sale of the painting immediately after Louis died in 1826. Louis worked on this painting extremely hard, returning to it many times which is why there is partly feeling of coarseness.
