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.
