Vibius Macer during his years of active service.Military "armillae" were modelled on those worn by the Celts.The tradition of using Celtic-style torcs and "armillae" as Roman military decorations had its beginnings in 361 BC when Titus Manlius Torquatus (consul 347 BC) slew a Gallic chieftain of impressive size in single combat.
