I understand that the term "decurion" originally was applied to either an infantry or a cavalry leader of 10, but that in time, it came to mean a cavalry squadron commander (30 men & their mounts), and that an infantry "patrol leader" of 8 (one contubernium--no longer 10) came to be called a "decanus." If this is correct, please confirm it. If not, please correct it. If correct, when did the term "decanus" come into usage?
