Flavius Aetius
Bucellarii (the Latin plural of "Bucellarius"; literally "biscuit–eater", "") were formations of escort troops used in the Roman Empire in Late Antiquity. They were employed by high-ranking military figures (such as Flavius Aetius and Belisarius) or civil office-holders. The word is derived from the type of bread rations eaten by these troops, so-called "buccellatum". The term "bucellarii" came into common use during the reign of Emperor Honorius ().
