How to treat the relationship between famous paintings of human body art and vulgarity?

I remember one day 20 years ago, I was leafing through a collection of western classic oil paintings in the university library. When I saw The Fountain of Anger, I was shocked at once! To tell the truth, this is the first time in my life to appreciate human body art oil painting. I never thought that the human body was so beautiful, nor did I think that the human body art oil painting was so beautiful, and I never thought that the painter could express the human body so beautifully!

Fountain is the representative work of Angel, the chief representative of French neo-classical painting masters in the19th century. It is a human body oil painting that has been revised many times from 1830 to 1856 after 26 years. 76-year-old Angel looked at this painting and cried incessantly. He devoted half his life to it, which fully demonstrated his artistic attainments and embodied his aesthetic accomplishment and sentiment.

In the picture, a beautiful girl holds a purple clay bottle filled with spring water, and her legs are slightly bent, standing in a dark green niche in a vertical configuration, showing the unique curvaceous beauty of young women. The girl's expression is very simple, facing forward, and there is a pure and innocent charm in her bright eyes. The painter painted a girl's vibrant skin with a dull velvet brush stroke. The clear and transparent spring water pouring out of the pottery bottle adds flowing rhythm to the calm picture, and at the same time, it also sets off the girl's bright face and reflects the girl's innocent heart.

It's beautiful! This is a pure beauty, a pure beauty, an elegant beauty, a solemn beauty, a refined beauty! In front of such a beautiful, holy and elegant human body art oil painting, the viewer will get a clear mind, have a pleasure of visual beauty, lament the perfection of the human body, and will not give birth to other boring ideas.

Fountain is regarded as a classic of human body art oil painting by many national academies of fine arts, and is listed as a model of art and human body art teaching. Now it is collected in the famous Louvre in Paris, and it has become a treasure of the Louvre together with Leonardo da Vinci's Mona Lisa.

I think that a painting that can become a famous painting of human body art should be a masterpiece and classic that has been tested by countless people for many years. It should have the same elegant and solemn quality and atmosphere as "spring", but also stay away from vulgarity, cultivate people's hearts and enjoy beautiful enjoyment.
