Famous quotes containing the words spiral and/or curved:
“Year after year beheld the silent toil
That spread his lustrous coil;
Still as the spiral grew,
He left the past year’s dwelling for the new,
Stole with soft step its shining archway through,
Built up its idle door,
Stretched in his last-found home, and knew the old no more.”
—Oliver Wendell Holmes, Sr. (1809–1894)
“By constant dripping, water hollows stone,
A signet-ring from use alone grows thin,
And the curved plowshare by soft earth is worn.”
—Ovid (Publius Ovidius Naso)
