Henry Wadsworth Longfellow Quote

The shades of night were falling fast,
As though an Alpine village passed
A youth, who bore, 'mid snow and ice,
A banner with the strange device,
Excelsior!

His brow was sad; his eye beneath,
Flashed like a falchion from its sheath,
And like a silver clarion rung
The accents of that unknown tongue,
Excelsior!
