The mariner remembers when a child,
on his first voyage, he saw it fade and sink
And when returning from adventures wild,
He saw it rise again o’er ocean’s brink.

Steadfast, serene, immovable, the same,
Year after year, through all the silent night
Burns on forevermore that quenchless flame,
Shines on that inextinguishable light!

Henry Wadsworth Longfellow, "The Lighthouse"
