The story of Archimedes
Archimedes was the resident of the city-state of Syracuse on the east coast of Sicily, founded in 734 BCE. During his time the state was a powerhouse of art, science, and commerce even rivaling Athens.
Archimedes shared a close relationship with the king and was often called to suggest solutions to civic problems within the city. From inventing a water pump to remove rainwater from ships to testing the amount of gold in the king’s crown (remember the Eureka moment when he ran naked?), Archimedes’s brilliance made him the most respected scientist of his time.
It was around this time that the Romans attacked the state. A huge Roman army under their famous general Marcellus laid siege outside the walls of Syracuse. Well versed in siege warfare, the Romans expected the conquering of the city-state to be a cakewalk as ships carrying ladders and grappling hooks sailed toward the city with the intention of scaling its walls.
But they had grossly underestimated the brilliance of Archimedes. Archimedes devised a series of devious engineering marvels that repulsed Marcellus and his army in every assault. What was expected to finish in two days went on for two years with the Roman army waiting outside the walls, frustrated and terrorized by a ‘local’ engineer as they called Archimedes.
Some of his marvelous creations were simply too brilliant even for today’s times.
The Archimedes Claw
The Archimedes Claw was a notorious invention in which huge beams could be swung out over the walls and some of also dropped huge weights, punching holes through the ships and sinking them.
Others had a claw or grappling hook, which grabbed hold of the rigging or rails of a galley, raising it, shaking it, and capsizing it. The terrifying spectacle of a ship being lifted and thrown stuck terror within the Romans.
The Archimedes Catapult Engine
The historian Plutarch describes the catapult engine as a series of “engines” designed to hurl arrows and rocks at attacking Roman troops and ships.
According to him, some of the rocks hurled from Archimedes’s catapults weighed as much as 10 talents — around 700 pounds. He also describes different types of catapult engines with varied ability to hurl or shoot projectiles at attackers both at great range and directly under the city’s walls.
The Archimedes Death Ray
This was the most lethal of Archimedes inventions. The invention involved a huge mirror that could focus sunlight onto the wooden Roman ships and cause them to burst into flames.
The device consisted of a large array of highly polished bronze or copper shields arranged in a parabola, concentrating sunlight into a single, intense beam. This single device spread havoc among Roman sailors who even mutinied rather than getting burnt to death.
Marcellus could not afford any more direct attacks and he suffered heavy losses. What began as a short siege had become a stalemate that went on for two years.
