The lorica hamata (in Latin with normal elision: [loːr̺iːk‿(h)aːmaːt̪a]) is a type of mail armor used by soldiers[1] for over 600 years (3rd century BC to 4th century AD) from the Roman Republic to the Roman Empire.[2] Lorica hamata comes from the Latin hamatus (hooked) from hamus which means "hook", as the rings hook into one another.
