One of the first fibula designs of the Roman-era began in the La Tene III era, in the late 1st century BC. The Straight Wire fibula, also known as the Soldier's type or Legionnaire's type, is a very plain design. It resembles the violin bow fibula of over one thousand years earlier except that the bow has slightly more of an arch and the spring in (short) bilateral not unilateral. The Straight Wire fibula is found through the 1st century AD.
