Famous quotes containing the word airy:
“My aspens dear, whose airy cages quelled,
Quelled or quenched in leaves the leaping sun,
All felled, felled, are all felled;”

“We are little airy creatures,
All of different voice and features:
One of us in glass is set,
One of us you’ll find in jet,
T’other you may see in tin,
And the fourth a box within;
If the fifth you should pursue,
It can never fly from you.”
—Jonathan Swift (1667–1745)

In airy dalliance,
Precipitate in love....”
