Throughout history, dramatic theater has evolved, changing and adapting to the preferences, economy and political atmosphere of the current society. However, one specific aspect of theater has remained constant; the protagonist of story line often requires the help of an assistant. Whether it's a superhero and his sidekick or a socialite and her personal secretary, there is frequently a loyal companion who faithfully remains at the side of the main character - and the success of the protagonist relies on their aid of his/her sidekick. .
Playwrights of Italian theater applied this concept throughout many of their works, often utilizing the concept of a young master and his dutiful servant. Whether the young master finds himself in a troublesome situation, or is too love struck to develop a scheme in order to be with his lover, the servant is there to make sure his master is successful in his ventures. Thus, it is no wonder that the relationship between the young master and his servant is seen in old Roman comedy, such as "Mostellaria", and the Commedia Dell'Arte production of "The Lady who was Believed Dead". While the characters may change, it is the versatility of the relationship that has given this dynamic longevity.
The relationship between the young master and his servant is often one much like that of a child and his caretaker. However, as a caretaker usually keeps a child out of trouble, it is often the servant's task to keep their young master out of trouble they've already gotten themselves into. For most servants who find themselves in this particular situation, it is simply their duty to help their young master. However, in Plautus' Mostellaria, the servant, Tranio, simultaneously played a role in getting his master into trouble as well as trying to get him out. While young Philolaches father, Theuropedis, is away, he leaves Tranio with the task of watching after his son and keeping him from getting into trouble.
