Vexillarius was one of the signiferi in the Roman legion and was specially protected during combat. He was defended with a small parma shield.
His task was to carry vexillum (pl vexilla), a military banner representing the name and emblem of the legion. The banner consisted of a fabric hanging on the crossbar of a lance or a stick. It was used both in infantry and in riding.
The legionary cavalry had banners on a horizontal pole.
