Famous quotes containing the words dead and/or walking:
“Look. And the dancers move
On the departed, snow bushed green, wanton in moon light
As a dust of pigeons. Exulting, the grave hooved
Horses, centaur dead, turn and tread the drenched white
Paddocks in the farms of birds. The dead oak walks for love.”
—Dylan Thomas (1914–1953)
“How selfhood begins with a walking away,
And love is proved in the letting go.”
—C. Day Lewis (20th century)
