Famous quotes containing the words code and/or letters:
“Wise Draco comes, deep in the midnight roll
Of black artillery; he comes, though late;
In code corroborating Calvin’s creed
And cynic tyrannies of honest kings;
He comes, nor parlies; and the Town, redeemed,
Gives thanks devout; nor, being thankful, heeds
The grimy slur on the Republic’s faith implied,
Which holds that Man is naturally good,
And—more—is Nature’s Roman, never to be
scourged.”
—Herman Melville (1819–1891)
“The post-office had a great charm at one period of our lives. When you have lived to my age, you will begin to think letters are never worth going through the rain for.”
—Jane Austen (1775–1817)
