One of the most important artists of the 20th century is Francis Bacon. The formation of the works of the artist is important in terms of revealing the path and artistic phenomena. It is hoped that the findings will be a guide for new researches that can be done on this subject and for students who receive art education. The subject and purpose of the study is the visual analysis of the transformations of Francis Bacon's works from form to deformation, and to reveal which artists the artist used while creating his works, which methods he followed and what kind of style he created by passing all these through his own mind. The method of this study is theory-oriented field research. The literature on the subject has been scanned, and Bacon's studies describing the transformation from form to deformation have been examined and interpreted. It is seen that the works described by the artist have undergone a change from form to deformation. It can be said that this change has developed a new style as the artist assimilates the world he lives in. This change is directly proportional to the classical art form. It is understood that Bacon made use of optical views and expressive style while creating his own works. It is observed that the artist generally uses these effects in parts such as portraits and figures. It draws attention that the path the artist follows while describing his paintings is a transformation from form to deformation. This transformation stands out not as a known deformation, but as works that the artist has acquired through his own personal experiences, assimilated and evolved into a completely different dimension. Bacon has created his own works based on the works of different artists in his paintings. The artist took Biomorphic structure from Picasso, bodily form in suffering from Matthias Grünewald, changes in the body showing pain, death and horror from Francis Goya, dramatic effects from Rembrandt and Soutine showing dismembered skins, faces and limbs. The concept of time has an important place in Bacon's works and he created this concept by taking advantage of the tragedy in the book "Being and Time" by the artist Martin Heiddegger. In addition, color is an important element in the works of the artist. Based on the pastel tones used by Edgar Degas, it can be said that Bacon applied these color tones in his own works. It has been concluded that the artist has benefited from the works of different artists, both technically and formally, as well as from the information obtained in sociological, psychological and philosophical ways, and the artist creates an artistic language by passing all these points through his own mental filter.
