All the beautiful, brave
Colors that curled in the wave–
Flooding ground purple and crimsoning air–
Are battered and rigid and bare.

Angrier than a tiger. With
Each wave the sea sends to batter
Him, he sinks new roots in the earth.

And lights the little mound;
But when she ventures there,
The black and threatening branches wave her back,
And guard the ghostly ground.

That tops the church-yard, sighing!
For sighing oft it seems to be,
And as its waving leaves, around,
With morning's tears begem the ground
The Zephyr trembles, flying!
"The Deserted Cottage" by Mary Darby Robinson

Waves close in front, woods close behind,
Green shutters, whitewashed walls;
A little space of rocky ground,
Where climbs the wave, and, round and round
The seagull curves and calls.
"At Shelley’s House At Lerici" by Alfred Austin
The blades of heroes fence it round,
Where'er it springs is holy ground;
From tower and dome its glories spread;
It waves where lonely sentries tread;
It makes the land as ocean free,
And plants an empire on the sea!
"The Flower of Liberty" by Oliver Wendell Holmes
