The iambic trimeter was imitated in Latin by 2nd century BC comic playwrights such as
Plautus and
Terence, where it is known as the iambic senarius. It is the most commonly used meter in their plays, especially in Terence, and it is the only meter which was used purely for dialogue without musical accompaniment. It was the preferred meter of the Roman fabulist
Phaedrus in the first century AD. In Latin the basic meter was as follows: :| x – x – | x – x – | x – u – | That is to say, the third and seventh elements, which were always short in Greek tragedy (but not in Greek comedy), were
anceps (either long or short) in Latin; in fact they are long 60% of the time, while the Greek
anceps syllables (the first, fifth, and ninth elements) are long in 80–90% of lines. As in the Greek trimeter, any long or
anceps syllable except the last could be replaced with a double short syllable (u u). As in Greek, there was usually (though not always) a
caesura (word-break) after the fifth element. An example of a Latin iambic senarius (from the prologue to Plautus'
Aulularia) is the following: : :| – – – – | – – – – | – – u – | :"In case anyone should wonder who I am, let me explain in a few words." A difference between Latin and Greek iambics was that the Latin senarius was partly accentual, that is to say the words were arranged in such a way that very often (especially in the first half of the verse), the word accents coincided with the strong points of the line, that is the 2nd, 4th, 6th etc. elements of the verse. Thus even in lines where nearly all the syllables were long as in the above verse, it is possible to feel the iambic rhythm of the line. Any long or
anceps element except the last could be
resolved into two short syllables, giving rise to lines like the following (the resolved elements are underlined): : : | – uu – uu | – uu – – | uu – u – | :"Right now today Amphitryon will come here from the army" The above line also illustrates another feature found in Plautus and Terence, namely iambic shortening or , where the syllables
ab ex- are scanned as two short syllables. The long ē in is another Plautine feature. ==Accentual-syllabic iambic trimeter==
