Stephen King

'Salem's Lot

Successive nations perchance have drank at, admired, and fathomed it, and passed away, and still its water is green and pellucid as ever.

Henry David Thoreau

Walden

Again old heart so gay, again to you, your sense, the full flush spring returning, Again the freshness and the odors, again Virginia’s summer sky, pellucid blue and silver, Again the forenoon purple of the hills, Again the deathless grass, so noiseless soft and green, Again the blood-red roses blooming.

Walt Whitman

Leaves of Grass

"Hard is the task, and rare," (the queen rejoin'd,) Impending destinies in dreams to find; Immured within the silent bower of sleep, Two portals firm the various phantoms keep; Of ivory one; whence flit, to mock the brain, Of winged lies a light fantastic train; The gate opposed pellucid valves adorn, And columns fair incased with polish'd horn; Where images of truth for passage wait, With visions manifest of future fate.
