“O sleep! it is a gentle thing,
Beloved from pole to pole!”

—The Rime of the Ancient Mariner, Samuel Taylor Coleridge

“I only know that while I sleep I have no fear, nor hope,
nor trouble, nor glory. God bless the inventor of sleep.”

—Don Quixote, Miguel de Cervantes

“I wish I could write a chapter upon sleep … and yet,
as fine as it is, I would undertake to write a dozen chapters
upon button-holes, both quicker and with more fame,
than a single chapter upon this.

—The Life and Opinions of Tristram Shandy, Laurence Sterne
