The reading process in comics is an extension of text. In text alone the process of reading involves word-to-image conversion. Comics accelerate that by providing the image. When properly executed, it goes beyond conversion and speed and becomes a seamless whole. In every sense, this misnamed form of reading is entitled to be regarded as literature because the images are employed as a language. There is a recognizable relationship to the iconography and pictographs of oriental writing. When this language is employed as a conveyance of ideas and information, it separates itself from mindless visual entertainment. This makes comics a storytelling medium.
