15. _Poenulus_.--The original was a Greek play, Καρχηδόνιος, the author of which is unknown, as the fragments of Menander's Καρχηδόνιος do not fit in with Plautus' play. The play was called by Plautus 'Patruus,' but posterity went back to the older name 'Poenulus.' Prol. 53, 'Carchedonius vocatur haec comoedia Graece, Latine Patruus Pultiphagonidae.'[10] Authorities assign the play to B.C. 189. The play is considerably interpolated, one ending being at l. 1371, another at l. 1422, whence some authorities have considered ll. 1372-1422 as spurious. Ritschl thinks that the two endings are about the same age, and compares the double ending of the _Andria_ of Terence. The play is noted for the two Carthaginian renderings of the soliloquy of Hanno, ll. 930-9, and ll. 940-9. The scene is Calydon in Aetolia. 16. _Persa_.--This play, the original of which is unknown, has been variously assigned to 197 and 186 B.C. The play shows traces of two distinct editions. The scene is Athens. 17. _Rudens_.--This play has been assigned to about B.C. 192. The original is by Diphilus; and the scene is Cyrene. Prol., 1. 32, 'Primumdum huic esse nomen urbi Diphilus Cyrenas voluit.' 18. _Stichus_, performed B.C. 200 _ludis plebeis_, as we learn from the didascalia, 'Graeca Adelphoe Menandru acta ludis plebeis Cn. Baebio C. Terentio aed. pl. ... C. Sulpicio C. Aurelio coss.' This cannot be the _Adelphi_ imitated by Terence, the fragments of which do not bear the least resemblance to the _Stichus_. It may be a second _Adelphi_ by Menander. Others read 'Philadelphoe' in the above didascalia. Part of the play has been lost, and it shows traces of two distinct editions. The scene is Athens. 19. _Trinummus_.--The original was Philemon's Θησαυρός, as seen from the didascalia, 'Graeca Thensaurus Philemonis acta ludis Megalensibus.' Some indication of the date is got from l. 990, 'Vapulabis meo arbitratud et novorum aedilium.' The only festival that would suit the term _novi aediles_ is the _ludi Megalenses_[11] as from B.C. 266 to 153 the new magistrates entered on office on the Ides of March. This festival was not of a scenic character till B.C. 194, consequently the _Trinummus_ must be after that date. The mention of Syrian slaves in l. 542 also makes it probable that this is one of the latest works of Plautus. The scene is Athens. 20. _Truculentus_.--The original is unknown. The play was written in Plautus' old age, probably about B.C. 189. The text has suffered greatly. The scene is Athens. 21. _Vidularia_.--Only fragments are extant. It is thought to have been modelled on a play called Σχεδία by Menander.
