Villanelle of Change by Edwin Arlington Robinson

SINCE Persia fell at Marathon, / The yellow years have gathered fast:

Long centuries have come and gone.

And yet (they say) the place will don

A phantom fury of the past,

Since Persia fell at Marathon; / And as of old, when Helicon

Trembled and swayed with rapture vast

(Long centuries have come and gone), / This ancient plain, when night comes on,

Shakes to a ghostly battle-blast, / Since Persia fell at Marathon.

But into soundless Acheron

The glory of Greek shame was cast:

Long centuries have come and gone,

The suns of Hellas have all shone, / The first has fallen to the last: -

Since Persia fell at Marathon, / Long centuries have come and gone.
