According to The Rhetoric of the Image, images are rhetorical. There are different “signs” that are communicated through visual artifacts. These signs come together to form a coherent whole with rhetorical meaning which portrays values, culture, and much more. A rhetorical analysis also shows that there may be multiple meanings to a visual artifact. Barthes believes that there is always a linguistic message, even in an image. He also says that there is also always a not so obvious symbolic or literal image within an image, a hidden meaning you could say. Basically, a visual artifact can be the same as any other rhetorical object and can be analyzed as such.
I agree with the fact that Barthes believes images and visual artifacts to be rhetorical. As a rhetoric and professional writing student, I believe that anything can be rhetorical and can be rhetorically analyzed. I enjoyed seeing that a scholar also agrees with me on this point.
