2647. This verse is confined to the early drama, where it is employed as
a _clausula_ (2536), especially with Cretics. It consists of three
complete trochaic feet. The same substitutions are admitted in every
foot that are allowed in the first two feet of the Ternarius (2644). An
example is:--
Haú bonŭm | teneō | sérvom
-́ ⏑ | ⏑̇ ⏑ > | -́ ⏑ (Pl. _Most._ 721).
This verse is sometimes called the _Ithyphallic_.
