This was the eventual replacement to The Pilum. Developed in 250 B.C. - the Spiculum was a cross between a Pilum and a German Bebra (similar to The Angon Spear of The Early Middle Ages). Another design modification which may owe it's existence to Germanic influences, it was considered smaller and much lighter. It's spearhead was considerably smaller as well. It was used primarily as a stabbing/thrusting weapon. It did not follow the same principle as The Pilum, in that it did not bend upon impact (if thrown). They ranged from 4 to 5 feet long. They saw some popularity among Roman cavalry. They would cease being used by 400 A.D.
