Ars Amatoria
Though most of this book is rather tongue-in-cheek, some people didn't take it that way and this could be the reason or part of the reason why Ovid was banished from Rome. However, his banishment probably has more to do with the "Ars Amatoria", written later, which offended Augustus. There is also a connection between Ovid and Augustus' daughter, Julia, who was also exiled.
