Dactylic hexameter is a line of poetry built from six metrical feet, usually using dactyls, which are one stressed syllable followed by two unstressed syllables. In classical Greek and Latin epic, it was the standard meter for long narrative poems, often allowing substitutions that give the line flexibility while preserving its steady, rolling movement. The final foot is typically shortened.
Example
Sing through the bright, wide morning and follow the road to the harbor
Waves on the stone and the gulls in the wind and the cry of the anchors
