Famous quotes containing the words grey and/or gold:
“Each had his past shut in him like the leaves of a book known to him by heart; and his friends could only read the title, James Spalding, or Charles Budgeon, and the passengers going the opposite way could read nothing at all—save “a man with a red moustache,” “a young man in grey smoking a pipe.””
—Virginia Woolf (1882–1941)
“‘Tis not the balm, the sceptre, and the ball,
The sword, the mace, the crown imperial,
The intertissued robe of gold and pearl,
...
Not all these, laid in bed majestical,
Can sleep so soundly as the wretched slave
Who with a body filled and vacant mind
Gets him to rest, crammed with distressful bread.”
—William Shakespeare (1564–1616)
