An example is:--

Rū|pḗre | nec mā|tér do|mum # caérula | tḗ reve|hét

(H. _Epod._ 13, 16).

2679. This verse occurs only in the Second Archilochian Strophe (2726)

of Horace. Some authorities treat the first colon as an iambic dimeter.

The name Iambelegus was given to the verse because the ancient

grammarians regarded it as a dactylic pentameter for the first half of

which an iambic colon had been substituted.
