Aeneas Tacticus

Aeneas Tacticus (; 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. Polybius described his design for a hydraulic semaphore system.

According to Aelianus Tacticus and Polybius, he wrote a number of treatises () on the subject. The only extant one, ''How to Survive under Siege'' (, ), deals with the best methods of defending a fortified city. An epitome of the whole was made by Cineas, minister of Pyrrhus, king of Epirus. The work is chiefly valuable as containing a large number of historical illustrations.

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). Provided by Wikipedia
