🔺 THE TRIBULUS 

The tribulus, or caltrop, was a simple yet effective anti-personnel weapon made of iron or wood with sharp spikes arranged so one always pointed up. 

Romans used them to hinder enemy troops, especially cavalry and chariots, by injuring feet and hooves. Easy to deploy defensively or offensively, they created battlefield chaos. 

Called "murex ferreus" (jagged iron) by Romans, the name "tribulus" comes from Greek for "three spikes," though Roman versions usually had four.

They are even being used in modern times.
