The Cornuti Seniores were often brigaded with the Brachiati Seniores. The Cornuti were one of the First Palatina unit, founded by Constantine somewhere around 310 AD. They may have originated from the Auxiliaries on the Rhine frontier, and maintained the old-style Palatina structure. The Cornuti are organized into 80-man centuries, and consist of 4 Pedites units and 2 Lanciarii units. This totals a Numerus of 480 men.
The Cornuti (“horned”) was an auxilia palatina unit of the Late Roman army, active in the 4th and 5th century. It was probably related to the Cornuti seniores and the Cornuti iuniores.
According to some scholars, they are depicted on the Arch of Constantine, as the Germanic soldiers who are shown wearing horned helmets. On the relief representing the Battle of Verona (312) they are in the first lines, and they are depicted fighting with the bowmen in the relief of the Battle of the Milvian Bridge.
