It would add greatly to our interest in the plays of Plautus if we knew more about the order in which they were produced. As it is, our knowledge of the dates of the plays is pitifully meagre and uncertain. Miles Gloriosus appears to have been produced soon after 206; Cistellaria about 201; Stichus (the only play that can be dated with certainty) in 200; Trinummus soon after 194; Pseudolus probably is 191, and Truculentus about 189. The date of the remaining seventeen plays is unknown. We can only infer their relation one to another from the internal evidence of language, metre, and structure. The results of an examination on these lines, if they converged, might be useful in enabling us to arrange the plays roughly in a number of well-defined groups. Mr. Sedgwick 1 has recently made an interesting attempt to approach the problem from the side of metre. I think that a more intensive study of the plays from the side of language might lead to profitable results. My immediate concern is, however, only with a small corner of this vast field—viz., the frequent coincidence of thought and phrase which is so marked a feature of these plays.
