"While stands the Coliseum, Rome shall stand;

When falls the Coliseum, Rome shall fall;

And when Rome falls—the world."

Lord Byron 1788-1824: Childe Harold's Pilgrimage. Canto iv. Stanza 145.

While Thee I seek, protecting Power,

Be my vain wishes stilled;

And may this consecrated hour

With better hopes be filled.

Helen Maria Williams (1762-1827): Trust in Providence.

While there is life there's hope, he cried.

John Gay (1688-1732): Fables. Part i. The Sick Man and the Angel.
