Aene'as or Aene'as Tacticus（*Ai)nei/as), surnamed TACTICUS (ὁ Τακτικός), a Greek writer, whose precise date is not known. Xenophon (Xenoph. Hell. 7.3.1) mentions an Aeneas of Stymphalus, who about the time of the battle of Mantineia (362, B. C.) distinguished himself by his bravery and skill as general of the Arcadians. Casaubon supposes this Aeneas to be the same, and the supposition is confirmed by a passage (Comment. Poliorc. 27) where he speaks familiarly of an Arcadian provincialism.
WorksBut, however this may be, the general character of this work, the names he mentions, and the historical notices which occur, with other internal evidence, all point to about this period.
στρατηγικὰ βιβλία, or περὶ τῶν στρατηγικῶν ὑπομνήματα (Plb. 10.40; Suidas, s. v. Αἰνείας), consisting of several parts. Of these only one is preserved, called τακτικόν τε καί πολιορκητικόν ὑπόμνημα περί τοῦ πως χρή πολιορκούμενον ἀντέχειν, commonly called Commentarius Poliorceticus. The object of the book is to shew how a siege should be resisted, the various kinds of instruments to be used, manœuvres to be practised, ways of sending letters without being detected, and without even the bearers knowing about it (c. 31, a very curious one), &c. It contains a good deal of information on many points in archæology, and is especially valuable as containing a large stock of words and technical terms connected with warfare, denoting instruments, &c., which are not to be found in any other work. From the same circumstance, many passages are difficult.
