Green is the prime color of the world, and that from which its loveliness arises.
Pedro Calderon de la BarcaNo virtue can be real that has not been tried. The gold in the crucible alone is perfect; the loadstone tests the steel, and the diamond is tried by the diamond, while metals gleam the brighter in the furnace.
Pedro Calderon de la BarcaAnd yet, and yet, in these our ghostly lives, Half night, half day, half sleeping, half awake, How if our waking life, like that of sleep, Be all a dream in that eternal life To which we wake not till we sleep in death
