David is the concrete embodiment of Renaissance humanism. On the surface, it praises the human body, which is a "revival" of ancient Greek art. In essence, it means that people are freed from the shackles of the dark Middle Ages and fully realize the great power of people to transform the world. Michelangelo injected great enthusiasm into the carving process, creating not only a statue, but also a symbol of artistic expression of the ideological emancipation movement. As the highest realm of sculpture works of an era, David always radiates endless brilliance in the history of art.

People's minds were liberated, and before that, paintings like religion had a halo. Humanism is to liberate human nature from feudal religion. Both pictures show that their social thoughts have been liberated, but they are not so feudal. Mona Lisa is a businessman. It can better reflect the humanistic color.
