Famous quotes containing the words cloud and/or base:
“When the lamp is shattered,
The light in the dust lies dead;
When the cloud is scattered,
The rainbow’s glory is shed;
When the lute is broken,
Sweet tones are remembered not;
When the lips have spoken,
Loved accents are soon forgot.”
—Percy Bysshe Shelley (1792–1822)
“Study is like the heaven’s glorious sun,
That will not be deep searched with saucy looks;
Small have continual plodders ever won,
Save base authority from others’ books.”
—William Shakespeare (1564–1616)
