Sylloge Tacticorum is thought to have been written in the middle of the tenth century. It is a work on the making of order and organization of military forces and ways to outwit and overcome opponents in the field of battle.
It contained a description of tactics which would later serve as an influence on the tactical system described in Praecepta Militaria by Nikephoros II Phokas.
The word sylloge means, in Greek, a gathering of information on something.
