Famous quotes containing the words gray and/or fossil:
“When you are old and gray and full of sleep,
And nodding by the fire, take down this book,”
—William Butler Yeats (1865–1939)
“The earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree, which precede flowers and fruit,—not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic.”
—Henry David Thoreau (1817–1862)
