We don't know much about the life of Aristophanes other than what we can learn through his plays. He wrote 40 plays but only 11 of them still survive. He was a great comic playwright, and through him we get a more complete picture of daily life in Ancient Athens.
One notable thing about Aristophanes is that he wasn't afraid to get in a fight with some of the heavies of the day. In 'Clouds' he mercilessly lampoons Socrates and had previously mixed it up with other powerful members of Athenian society. I don't know how much this effect this has on his repeatability score. No one else really does either. One of the challenges of piecing together Ancient history is that there are few accounts and it isn't always easy to tell which one is definitive.
