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 Europes strand
A living image of our own bright land,
Such as upon thy glorious canvas lies;”
—William Cullen Bryant (17941878)
“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctors hat until its grey like a dunces cap.”
—Franz Grillparzer (17911872)
