Late Roman Unit Sizes

[Julian de Vries]

Some time ago I can faintly recall reading something saying that Urbicius reorganized the army under Anastasius, also Andronicus (?) in the sixth century also seems to have reorganized the army by studying the ancient Greek army manuals. I am not really sure about all of this, since it has been some time, so I should find the appropriate primary sources. Whatever the case, there is one other army reorganization that I am pursuing right now, that is the so called modular brick tagmatic system of Marcel Frederik Schwarze. This system can be seen in the Sylloge Tacticorum of emperor Leo VI and also presumably in the Strategicon of emperor Mauricius (did this system perhaps start with him?). The tagmatic modular brick system is quite some novelty, which I cannot yet place, should it be 6th century or 5th century, is this system seen in the Anastasius Perge list? I don't know.
