“Shall the Spring dawn, and she still clad in smiles,
And with an unscathed brow,
Rest in the strong arms of her palm-crowned isles,
As fair and free as now?
We know not; in the temple of the Fates
God has inscribed her doom;
And, all untroubled in her faith, she waits
The triumph or the tomb.”
—Henry Timrod (18281867)
