Born in a musical family, Klee has a high musical quality. He once made a difficult choice between painting and music, and later chose painting. He is the main member of the "Green Knight" painting school organized by Kandinsky, but unlike Kandinsky, he has not moved towards the abstract painting style of completely eliminating objects. He also explores the art of expressing painting beyond objects, but generally speaking, his painting styles are changeable and diverse, and it is difficult to plan into any specific art school. In the history of western painting, Klee is highly respected for his excellent use of colors and lines, and the use of some mysterious symbolic languages in painting is also his most prominent feature. Klee's works have a unique taste, and some people even comment that there is a childlike innocence. However, in fact, many works are painters' unique experience and insight into life after careful consideration. Kelly has a profound musical accomplishment, and he has a special study of architecture, which is reflected in his paintings, which reflects the harmony of music and the sense of balance, structure and lines of architecture. This painting "Death and Fire" was created in the last years of the painter's life, when the painter was seriously ill and dying. The picture is filled with a strong desolate and sad atmosphere, which is not a subjective guess, but the artistic appeal of the picture. The heavy black lines in the painting hide an unbearable heaviness. The pale figure with symbolic language in the middle, like a skull, makes people feel a sign of death. And if you look closely, you will find that the eyes and mouth of this image are composed of three letters: "T", "O" and "D", and the word "tod" composed of these three letters means death in German. Kelly handled this image very specially. On the one hand, he used a combination of pictures and words, which looked novel and interesting. On the other hand, this image is a left-facing person in outline, but it is for everyone in the treatment of five senses. This abnormal treatment makes the picture interesting and reflects the painter's unique humor. This distorted image seems to be the painter's helplessness and irony about life or death. This wonderful treatment also shows the painter's life interest, artistic talent and personality characteristics. On the right side of the picture, there is a little man like our hieroglyphics, which is made of thick lines and is stabbing the head. It is a symbol of virus or disease. The character's left hand holds up a circle, which is a symbol of the sun and time. It means that death is an inevitable outcome for anyone. It is just a process that the painter will face easily. As the painter wrote in a letter to a friend: "Of course, I am not on the road to death by accident. All my works point to one point and claim that the end is coming." Because of his profound understanding of life and death, the painter calmly faced it without losing his reason and his last banter and humor about life. The colors in the painting have a depressing sense of terror. The background of lux has a smell of death, and the pale characters seem to be patients sitting in blood. The color collocation of the whole picture has a stale smell of murals in ancient tombs, and various symbol languages also have a mysterious color and metaphysical taste. Klee's works have a fantastic color, not purely abstract or realistic, but a comprehensive art, an art of self dominated by the painter's unique personality. His painting language and style profoundly influenced many later painters.
