The Aeneid was written during a period of political unrest in Rome. The Roman republic had effectively been abolished, and Octavian (Augustus Caesar) had taken over as the leader of the new Roman empire. The Aeneid was written to praise Augustus by drawing parallels between him and the protagonist, Aeneas. Virgil does so by mirroring Caesar ...
"The Mathematics of Secrets Cryptography from Caesar Ciphers to Digital Encryption", to judge from the Google Books preview, uses the Caesar cipher as an introductory example. Books on cryptography often use it for this purpose because it's easy to understand and because it can be used to illustrate important concepts.
The Vigenère cipher uses a Caesar cipher with a different shift at each position in the text; the value of the shift is defined using a repeating keyword. [14] If the keyword is as long as the message, is chosen at random, never becomes known to anyone else, and is never reused, this is the one-time pad cipher, proven unbreakable. However the ...
Aeneas Flees Burning Troy, by Federico Barocci (1598). Galleria Borghese, Rome, Italy Map of Aeneas' fictional journey. The Aeneid (/ ɪ ˈ n iː ɪ d / ih-NEE-id; Latin: Aenēĭs [ae̯ˈneːɪs] or [ˈae̯neɪs]) is a Latin epic poem that tells the legendary story of Aeneas, a Trojan who fled the fall of Troy and travelled to Italy, where he became the ancestor of the Romans.

In the Aeneid (book II, 57 on), Aeneas recounts how Sinon was found outside Troy after the rest of the Greek army had sailed away, and brought to Priam by shepherds. He pretended to have deserted the Greeks and told the Trojans that the giant wooden horse the Greeks had left behind was intended as a gift to the gods to ensure their safe voyage home.
Caesar's forces launched a fierce counterattack, and soon put the Belgae to flight. Later, Caesar's troops entered Cicero's camp to find most of the men wounded. Meanwhile, Indutiomarus , a leader of the Treveri, began to harass Labienus's camp daily, eventually provoking Labienus to send out his cavalry with specific orders to kill Indutiomarus.
The code can be a consistent monoalphabetic substitution for the entire cipher or the disks can be moved periodically throughout the cipher making it polyalphabetic. For a monoalphabetic use, the sender and the person receiving the messages would agree on a cipher key setting (e.g., the "G" in the regular alphabet would be positioned next to ...
