This passage talks of the simplistic style Shakespeare used when writing Julius Caesar. This style is different in comparison to his earlier writings and helps show the advancements Shakespeare made as a writer.
Shakespeare’s first tragedy, Titus Andronicus, characterized his original skills. Trying to make it as ‘Roman’ as possible, he used elaborate words and highly expressive terms. The tragedy also had many references to mythology, making it obvious that Shakespeare was trying to produce the most eloquent representation of that time. This form of writing, however, was not necessary.
By the time Shakespeare wrote Julius Caesar, he realized that the Roman world did not have to be flattered and altered so as to make more exciting. Instead, writing of the plain, dry Roman world as it was would enable the true simplistic nature to be appreciated. Therefore, Shakespeare tried to create a simple portrayal of life in that time, which is why we, as a reader, notice an "apparent simplicity of style."
Overall, this passage shows how Shakespeare grew as a writer and had varying styles of writing, ranging from articulation to simplicity. He experimented with how to create the most accurate description and interpretation of the Roman world, and in the end, succeeding in doing so. For this reason, Julius Caesar is a clean cut and plain portrayal of life at that time.
