Pseudolus is a play by the ancient Roman playwright Titus Maccius Plautus. It is one of the earliest examples of Roman literature. The play begins with the shortest prologue of any of the known plays of Plautus, though it is not known whether Plautus wrote this prologue himself or if it was added later. Pseudolus was first shown in 191 B.C. during the Megalesian Festival, which was a celebration for the Greek Goddess Cybele. The temple for worship of Cybele in Rome was completed during the same year in time for the festival.
