What is the scene depicted in the Italian "The Prophess"?

The Italian prophetess depicts a street scene that Caravaggio accidentally saw. A gypsy woman, probably a vagrant who lives by divination, has the skill of palm reading of Kyrgyzstan, sly eyes, faint smile and gentlemanly grasp of a young man's hand. The composition of the whole work is concise, and two busts of a man and a woman are interlocking. Because only the bust of the character was depicted, all unnecessary details were deleted. Make the characters stand out.
