Definition: The pilum was a Roman legionary's six foot javelin, hurled at the enemy at the start of the engagement before using the sword. The pilum had a wooden shaft a yard long fitted with an iron head with a barbed point. The plural of pilum is pila. The Roman leader Marius altered construction so if the head of the pilum stuck in the enemy's shield, he would be unable to pull it out to re-use it. [Source: "The Genesis of Rome's Military Equipment," by S. McCartney; The Classical Weekly, Vol. 6, No. 10 (Dec. 21, 1912), pp. 74-79.] The Pilani (or Triarii), were originally troops who, standing behind the first two lines, held the pilum.

Polybius (Book VI) has this to say about the pilum:

" The pila are of two sorts — stout and fine. Of the stout ones some are round and a palm's length in diameter and others are a palm square. Fine pila, which they carry in addition to the stout ones, are like moderate-sized hunting-spears, 10 the length of the haft in all cases being about three cubits. Each is fitted with a barbed iron head of the same length as the haft. This they attach so securely to the haft, carrying the attachment halfway up the latter and fixing it with numerous rivets, that in action the iron will break sooner than become detached, although its thickness at the bottom where it comes in contact with the wood is a finger's breadth and a half; such great care do they take about attaching it firmly."
