On Canvas: Two Little Men

Two painters crossed my brow today; one, the neo-classicist David, the other the romanticist Delacroix.
I thought of them primarily because of their paintings of two little men; one, about five feet four inches, the other, one who stood a bit over five feet in height.
David, who became Napoleon's official painter, did two works that come to my attention because of the political implications in both.
Napoleon in His Study shows the great little man, standing in full uniform. As I recall, there is a clock on a mantel or some similar piece of furniture, to his right. With the lighting assigned to the painting, it is obviously at night. The clock shows a time representing the wee hours of the morning, suggesting that the Great Leader is available and in command twenty four hours of the day, every day.
The other painting shows Napoleon on a horse at an impossible upward angle conquering the heights, with the name of Hannibal in one corner of the painting.
Great painting, with a bit of propaganda suggested here, or what??
Delacroix painted the demonic genius of the violin, Paganini, in a small oil.
He also painted, in I believe 1839, both Chopin and his mistress George Sand (real name Dudevant). Actually, I believe it was done as a double painting; however, we remember the Chopin painting more clearly. I mused over the delicate treatment that Delacroix gives to Chopin's proboscis, as Chopin himself, at the end of his life, was purported to have complained that " I was cursed with a short life and a long nose."
Two little guys, both with huge impact upon our memory.
