Quick Facts About Roman Javelins
The Pilum: A heavy javelin of approximately 2 meters with a long iron shaft.
The Verutum: A shorter, lighter spear for light infantry (velites).
The Plumbata: A lead-weighted "super-dart" from the late antiquity.
- Tactics: Thrown at close range (15-30 meters) just before the sword charge.
The Verutum: The Weapon of the Velites
Before the heavy legionaries attacked, the enemy was bombarded by the velites. They used the Verutum.
Light and Agile: With a length of just 1.1 meters, velites could carry up to seven of these spears.
Hit-and-run: Ideal for skirmishing and proven effective against war elephants (like at Zama), because the throwing speed was higher than with the heavy pilum.
The Pilum: The Shield Breaker
The pilum was the masterpiece of Roman weapon-smithing. Its unique design with the long iron neck had a specific tactical purpose.
Penetration Power: Thanks to the weight (1 to 2.5 kg) concentrated behind a small pyramid-shaped point, the pilum could pierce armor and thick wooden shields.
Shield Disabling: If the pilum got stuck in a shield, the long iron shaft didn't always bend (as often thought), but it was impossible to cut off and made the shield top-heavy and unmanageable. The enemy had to drop their protection.
Weighted Variant: In the 1st century AD, versions appeared with a lead ball at the junction between wood and iron. This greatly increased the kinetic energy upon impact.
Tactical Use of the Pilum
The pilum was multi-functional and wasn't only thrown.
The Salvo: Legionaries threw their pila collectively at approximately 20 meters distance. This created a "rain of iron" that broke up the enemy formation just before the Romans closed in with their swords.
Anti-cavalry: At Pharsalus, the pilum proved its worth as a thrusting weapon. By using the spear like a lance, legionaries could prick mounted riders from their horses. The iron point at the bottom (butt-spike) helped anchor the spear firmly in the ground.
The Plumbata: The Deadly Dart
In the late Roman period (from the 3rd century AD onwards), warfare changed. The pilum was replaced by the Plumbata (also called martiobarbuli).
Construction: A short wooden shaft, weighted with a lead ball behind a barbed point, and fitted with feathers for stability.
Range: Because they could be thrown underhand or overhand with a large arc, they achieved much greater distance than the pilum.
Surprise Effect: Soldiers often carried five plumbatae on the inside of their shield. They could wound the enemy at great distance, even before the actual arrow or spear exchange began.
Frequently Asked Questions (FAQ)
Did the pilum really bend upon impact?
Although ancient sources claim this, experimental archaeology shows that the iron neck was often resilient enough not to break or deform completely. The effectiveness lay mainly in the fact that the long shaft pierced the shield and hindered the bearer.
How many javelins did a legionary carry?
During the Republic, it was usually two: one light and one heavy. In the later Imperial period, you often see depictions of soldiers with a single pilum, or later five small plumbatae.
Why was the pilum replaced by the plumbata?
Warfare became more defensive and infantry needed to bombard enemies at greater distance. The plumbata offered more range and was cheaper and more compact to produce in large quantities.
