Note 860 — Chapter XII · THE SWORD IN ANCIENT ROME; THE LEGION AND THE GLADIATOR.
Reading edition
The Clypeus, or Clipeus, of favourite Greek use, was also round, but larger than the Parma. Our ‘buckler’ (buccularius clypeus) takes its name from having on it an open mouth (bucca, buccula), in Chinese fashion, instead of the umbo.
