Tactica of Emperor Leo VI the Wise
The Tactica (Greek: Τακτικά) is a military treatise written by or on behalf of Byzantine Emperor Leo VI the Wise in c. 895–908 and later edited by his son, Constantine VII. Drawing on earlier authors such as Aelian, Onasander and the Strategikon of emperor Maurice, it is one of the major works on Byzantine military tactics, written on the eve of Byzantium's "age of reconquest". The original Greek title is τῶν ἐν πολέμοις τακτικῶν σύντομος παράδοσις ("short instruction of the tactics of war"). The Tactica elaborates on a wide variety of issues, such as infantry and cavalry formations, drills, siege and naval warfare etc. It is written in a legislative form of language and comprises 20 Constitutions (Διατάξεις Diataxeis) and an Epilogue and is concluded by 12 additional chapters, the latter mainly focusing on ancient tactics.
The text of the Tactica is transmitted in several manuscript prototypes, of which the most authoritative date to within a generation of Leo himself. Leo mentions within the Tactica, that Christianity could adopt Islam's doctrine of a "holy war" for its military applications.
An edition with English translation by G. T. Dennis (ed.), The Taktika of Leo VI. Text, Translation and Commentary ([CFHB 49] Dumbarton Oaks, Washington, D.C. 2010), was translated from a 10th-century Florentine manuscript.
