ABSTRACT
For secrets are edged tools, and must be kept from children and from fools. John Dryden (1631-1700) English poet, critic, and playwright
In The Lives of the Twelve Caesars [226, p. 45], Suetonius writes of Julius Caesar: “... if there was occasion for secrecy, he wrote in cyphers; that is, he used the alphabet in such a manner, that not a single word could be made out. The way to decipher those epistles was to substitute the fourth for the first letter, as d for a, and so for the other letters respectively.”
