Lorica plumata

While several types of loricae (armor) existed in the Roman legion, the lorica plumata was reserved for the use of military leaders (Tribunes and above, but typically Generals) due to the high cost of production, and maintenance. The name the Romans used for this type of armor is not known, lorica plumata being a descriptive term applied by modern scholars, referring to its resemblance to a bird's plumage.
