Final answer:
The Romans invented a device called a Corvus, which was a drawbridge-like device attached to the front of their ships. It allowed them to board enemy ships and engage in hand-to-hand combat.
Step-by-step explanation:
The Romans invented a device called a Corvus.
The Corvus was a drawbridge-like device that was attached to the front of Roman ships. It had a long, spiked end that could be extended and dropped onto the enemy ship, essentially creating a bridge between the two ships. This allowed the Roman soldiers to board the enemy ship and engage in hand-to-hand combat.
The Corvus was a highly effective weapon that the Romans used to gain an advantage in naval battles.
