Famous quotes containing the words blue and/or sun:
“I think I noticed once
T’was morning one sole street-lamp still bright-lit,
Which, with a senile grin, like an old dunce,
Vied the blue sky, and tried to rival it....”

“He will watch from dawn to gloom
The lake-reflected sun illume
The yellow bees in the ivy-bloom,
Nor heed nor see, what things they be;
But from these create he can
Forms more real than living man,
Nurslings of immortality!”
—Percy Bysshe Shelley (1792–1822)
