St John the Baptist was one of the famous paintings of Leonardo da Vinci. It was from the figures in the Bible: the Baptist John baptized Jesus at God's behest and when he scooped up the water in Jordan River, the sky was suddenly enlightened. And then a pigeon-shaped Holy Spirit appeared in the open sky. Then John followed the sermons of Jesus, and was named St John the Baptist. In the painting, the upper half body of the baptized John was naked and his whole body was in the darkness. Only his right arm, face, right hand and left hand were visible through the light. The baptized John had a long hair, like a young shepherd. He was holding a cross pointing to the sky with a cunning and mysterious smile in his face. Although this painting was about the traditional theme, the depiction of characters and background was unprecedented. In fact, John the Baptist pointed out the heaven in the darkness, revealing the depression and loss of the artist.
The painting St John the Baptist finished long before the death of da Vinci was beautiful and bright. Some people thought that St John’s archetype may be da Vinci's assistant and the manservant Chalet. St John the Baptist and Mona Lisa were both brought to the castle arranged by the king of France by da Vinci. Da Vinci always kept these two paintings until his death. The face of St John was so soft and charming that nobody could tell whether it was a man or a woman. Some people said John took male model as the prototype, and even the same sex close friend.
According to the Bible, St John was the cousin of Jesus Christ. Before preaching the gospel, Jesus Christ exhorted the repentance to the Jews and baptized for Jesus Christ. At the same time, he was also the prophet of Islam. In the Jordan River John baptized for people and made repentance, who was the forerunner of Christianity. The reform of Judaism and the prophesy of God's making the birth of important people were more important than himself and had laid a solid foundation for preaching.
