Famous quotes containing the words disk and/or head:
“Unloved, that beech will gather brown,
This maple burn itself away;
Unloved, the sun-flower, shining fair,
Ray round with flames her disk of seed,
And many a rose-carnation feed
With summer spice the humming air;”
—Alfred Tennyson (1809–1892)
“Each work of art excludes the world, concentrates attention on itself. For the time it is the only thing worth doing—to do just that; be it a sonnet, a statue, a landscape, an outline head of Caesar, or an oration. Presently we return to the sight of another that globes itself into a whole as did the first, for example, a beautiful garden; and nothing seems worth doing in life but laying out a garden.”
—Ralph Waldo Emerson (1803–1882)
