Sicily, which was wrested from Carthaginian control during the First Punic War (264-241 BC), was the first province of the Roman Republic not directly part of Italy. The Kingdom of Syracuse was an allied independent region in the south east of the island and a close ally of Rome during the long reign of King Hiero II. In 215 BC, Hiero's grandson, Hieronymus, came to the throne on his grandfather's death and Syracuse fell under the influence of an anti-Roman faction, including two of his uncles, amongst the Syracusan elite. Despite the assassination of Hieronymus and the removal of the pro-Carthaginian leaders, Rome's threatening reaction to the danger that a Syracusian alliance with Carthage would bring forced the new republican leaders of Syracuse to prepare for war.
Despite diplomatic attempts, war broke out between the Roman Republic and the Kingdom of Syracuse in 214 BC, while the Romans were still busy battling with Carthage at the height of the Second Punic War (218-201 BC).
A Roman force led by the General Marcus Claudius Marcellus consequently laid siege to the port city by sea and land. The city of Syracuse, located on the eastern coast of Sicily was renowned for its significant fortifications, great walls that protected the city from attack. Among the Syracuse defenders was the mathematician and scientist Archimedes.
The city was fiercely defended for many months against all the measures the Romans could bring to bear. Realizing how difficult the siege would be, the Romans brought their own unique devices and inventions to aid their assault. These included the
sambuca, a
floating siege tower with grappling hooks, as well as
ship mounted scaling ladders that were lowered with pulleys onto the city walls.
Despite these novel inventions, Archimedes devised defensive devices to counter the Roman efforts including a huge crane operated hook —
the Claw of Archimedes — that was used to lift the enemy ships out of the sea before dropping them to their doom. Legend has it that he also created a
giant mirror (see Heat ray) that was used to deflect the powerful Mediterranean sun onto the ships' sails, setting fire to them. These measures, along with the fire from ballistas and onagers mounted on the city walls, frustrated the Romans and forced them to attempt costly direct assaults.
