Famous quotes containing the word red:
“Here thou art painted in the dress
Of an inhuman murderess;
Examining upon our hearts
Thy fertile shop of cruel arts:
Engines more keen than ever yet
Adorned tyrant’s cabinet,
Of which the most tormenting are
Black eyes, red lips, and curled hair.”
—Andrew Marvell (1621–1678)
