Aeneas Tacticus[1] (Ancient Greek: Αἰνείας ὁ Τακτικός; fl.
4th century BC) was one of the earliest Greek writers on the art of war and is credited as the first author to provide a complete guide to securing military communications.
[3][4] According to Aelianus Tacticus and Polybius, he wrote a number of treatises (Ὑπομνήματα) on the subject.
The only extant one, How to Survive under Siege (Ancient Greek: Περὶ τοῦ πῶς χρὴ πολιορκουμένους ἀντέχειν, Perì toû pôs chrḕ poliorkouménous antéchein), deals with the best methods of defending a fortified city.
[5] Aeneas was considered by Isaac Casaubon to have been a contemporary of Xenophon and identical with the Arcadian general Aeneas of Stymphalus, whom Xenophon (Hellenica, vii.3) mentions as fighting at the Battle of Mantinea (362 BC).
