Famous quotes containing the word light:

    The light of memory, or rather the light that memory lends to things, is the palest light of all.... I am not quite sure whether I am dreaming or remembering, whether I have lived my life or dreamed it. Just as dreams do, memory makes me profoundly aware of the unreality, the evanescence of the world, a fleeting image in the moving water.
    Eugène Ionesco (b. 1912)

    Thine eyes shall see the light of distant skies:
    Yet, Cole! thy heart shall bear to Europe’s strand
    A living image of our own bright land,
    Such as upon thy glorious canvas lies;
    William Cullen Bryant (1794–1878)

    Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.
    Franz Grillparzer (1791–1872)
