Which work of Plautus has a large fragment that survives?

The work of Plautus that has a large fragment that survives is "Vidularia." This play is notable in the study of Roman comedy because the fragments that have been preserved provide insights into Plautus's style, themes, and the comedic devices he employed. It stands out among his works since it is less frequently performed or studied compared to others, yet contributes significantly to our understanding of Roman theatrical practices.

The other plays mentioned, while also written by Plautus, do not have as extensive surviving fragments. "Amphitryon," "Aulularia," and "Captivi" are more frequently discussed in the context of their complete structures and themes, but they do not possess the same level of preserved fragmentary content as "Vidularia." This makes "Vidularia" an important work for scholars focusing on the more niche aspects of Plautine comedy.
