allowed for grand gestures and extensive action to reach the audience members who were in the very back of the theater. However the Romans would have had to depend more on their voices than large physicality. There was not an orchestra available as there was for the Greeks and this is reflected in the notable lack of a chorus in Roman drama. The replacement character that acts as the chorus would in Greek drama is often called the "prologue". Goldberg says that "these changes fostered a different relationship between actors and the space in which they performed and also between them and their audiences". Actors were thrust into much closer audience interaction. Because of this, a certain acting style became required that is more familiar to modern audiences. Because they would have been in such close proximity to the actors, ancient Roman audiences would have wanted attention and direct acknowledgement from the actors. Because there was no orchestra, there was no space separating the audience from the stage. The audience could stand directly in front of the elevated wooden platform. This gave them the opportunity to look at the actors from a much different perspective. They would have seen every detail of the actor and heard every word he said. The audience member would have wanted that actor to speak directly to them. It was a part of the thrill of the performance, as it is to this day. Stock characters Plautus' range of characters was created through his use of various techniques, but probably the most important is his use of stock characters and situations in his various plays. He incorporates the same stock characters constantly, especially when the character type is amusing to the audience. As Walter Juniper wrote, "Everything, including artistic characterization and consistency of characterization, were sacrificed to humor, and character portrayal remained only where it was necessary for the success of the plot and humor to have a persona who stayed in character, and where the persona by his portrayal contributed to humor." For example, in Miles Gloriosus, the titular "braggart soldier" Pyrgopolynices only shows his vain and immodest side in the first act, while the parasite Artotrogus exaggerates Pyrgopolynices' achievements, creating more and more ludicrous claims that Pyrgopolynices agrees to without question. These two are perfect examples of the stock characters of the pompous soldier and the desperate parasite that appeared in Plautine comedies.
