Aelianus Tacticus in Wikipedia
Aelianus Tacticus (Ancient Greek: Αιλιανός Τακτικός) was a Greek military writer of the 2nd century, resident at Rome.
Aelian's military treatise in fifty-three chapters on the tactics of the Greeks, titled "On Tactical Arrays of the Greeks" (Περί Στρατηγικών Τάξεων Ελληνικών), is dedicated to Hadrian, though this is probably a mistake for Trajan, and the date 106 has been assigned to it. It is a handbook of Greek, i.e. Macedonian, drill and tactics as practiced by the Hellenistic successors of Alexander the Great. The author claims to have consulted all the best authorities, the most important of which was a lost treatise on the subject by Polybius. Perhaps the chief value of Aelian's work lies in his critical account of preceding works on the art of war, and in the fullness of his technical details in matters of drill.
He also gives a brief account of the constitution of a Roman army at that time. The work arose, he says, from a conversation he had with the emperor Nerva at Frontinus's house at Formiae. He promises a work on Naval Tactics also; but this, if it was written, is lost.
Critics of the 18th century — Guichard Folard and the Prince de Ligne — were unanimous in thinking Aelian greatly inferior to Arrian, but Aelian exercised a great influence both on his immediate successors, the Byzantines, and later on the Arabs, (who translated the text for their own use). Emperor Leo VI the Wise incorporated much of Aelian's text in his own work on the military art (Τέχνη Τακτική). The Arabic version of Aelian was made about 1350. It was first translated into Latin by Theodoras of Thessalonica, published in 1487.
In spite of its academic nature, the copious details to be found in the treatise rendered it of the highest value to the army organizers of the 16th century, who were engaged in fashioning a regular military system out of the semi-feudal systems of previous generations. The Macedonian phalanx of Aelian had many points of resemblance to the solid masses of pikemen and the squadrons of cavalry of the Spanish and Dutch systems, and the translations made in the 16th century formed the groundwork of numerous books on drill and tactics.
Moreover, his works, with those of Xenophon, Polybius, Onasander, Aeneas Tacticus and Arrian, were minutely studied by every soldier of the 16th and 17th centuries who wished to be master of his profession. It has been suggested that Aelian was the real author of most of Arrian's Tactica, and that the Taktike Theoria is a later revision of this original, but the theory is not generally accepted.
Aeliānus in Harpers Dictionary of Classical Antiquities
The Tactician, a Greek writer on war, about 100 A.D., composed a work dedicated to Trajan on the Greek order of battle, with special reference to Macedonian tactics (Τακτικὴ Θεωρία), which is extant both in its original and in an enlarged form. The original used falsely to be attributed to Arrian. See Köchly, De Libris Tacticis (1852).
