I'm not going to flesh out in any detail whatsoever what the plays are about. It's an adventure, go read. Moliere and Shakespeare based stuff on him. Rome's most successful playwright at his best? Dunno. I do know that these plays are funny especially The Braggart Soldier, The Brothers Menaechmus, The Haunted House and The Pot of Gold. Hell, that's all four! You need to act them out in your head with some understanding of the cultural context. The introduction helps with the context. The rest is up to you.
