It must strike every reader of Plautus, as worthy of note, that he assumes a certain knowledge of the Greek tongue on the part of his audience. Not only are many (chiefly commercial) terms directly imported from the Greek, as _dica_, _tarpessita_, _logi_, _sycophantia_, _agoranomus_, but a large number of Greek adjectives and adverbs are used, which it is impossible to suppose formed part of the general speech--e.g. _thalassicus_, _euscheme_, _dulice_, _dapsilis_: Greek puns are introduced, as "_opus est Chryso Chrysalo_" in the _Bacchides_; and in the _Persa_ we have the following hybrid title of a supposed Persian grandee, "_Vaniloquidorus Virginisvendonides Nugipolyloquides Argentiexterebronides Tedigniloquides Nummorumexpalpouides Quodsemelarripides Nunquamposteareddides_!" Nevertheless, Plautus never uses Greek words in the way so justly condemned by Horace, viz. to avoid the trouble of thinking out the proper Latin equivalent. He is as free from this bad habit as Cato himself: all his Graecisms, when not technical terms, have some humourous point; and, as far as we can judge, the good example set by him was followed by all his successors in the comic drama. Their superiority in this respect may be appreciated by comparing them with the extant fragments of Lucilius. In his metres he follows the Greek systems, but somewhat loosely. His iambics admit spondees, &c. into all places but the last; but some of his plays show much more care than others: the _Persa_ and _Stichus_ being the least accurate, the _Menaechmi_ peculiarly smooth and harmonious. The Trochaic tetrameter and the Cretic are also favourite rhythms; the former is well suited to the Latin language, its beat being much more easily distinguishable in a rapid dialogue than that of the Iambic. His metre is regulated partly by quantity, partly by accent; but his quantities do not vary as much as has been supposed. The irregularities consist chiefly of neglect of the laws of position, of final long vowels, of inflexional endings, and of double letters, which last, according to some grammarians, were not used until the time of Ennius. His Lyric metres are few, and very imperfectly elaborated. Those which he prefers are the Cretic and Bacchiac, though Dactylic and Choriambic systems are not wholly unknown. His works form a most valuable storehouse of old Latin words, idioms, and inflexions; and now that the most ancient MSS. have been scientifically studied, the true spelling of these forms has been re-established, and throws the greatest light on many important questions of philology.
