Hiero II of Syracuse
In 275 BC, the Syracusan army and citizens appointed Hiero commander-in-chief after Pyrrhus of Epirus left Sicily. He strengthened his position by marrying the daughter of Leptines, one of the leading citizens of Syracuse. This union connected him to powerful local families and secured political support within the city. Hiero later proved his military worth against the Mamertines, a body of mercenaries from Campania who had seized Messina as a base of operations. They harassed the Greeks around them until Hiero defeated them in a pitched battle near Mylae along the Longanus river. Carthaginian interference prevented him from capturing Messina itself, but he gained control over much of the territory. Between 275 and 271 BC, he seized total power in the city by allying himself with the people. Unlike past kings or tyrants of Syracuse, he ruled within the law and acknowledged the will of the assemblies. He never purged his opponents, which allowed him to maintain stability while consolidating authority.
Hiero was proclaimed king after a victory in 265 BC when fighting the Mamertines prior to the formal start of the First Punic War. The next year, the Mamertines became desperate and called for Roman aid. Hiero at once joined the Punic leader Hanno, who had recently landed in Sicily. Fighting a battle to an inconclusive outcome with the Romans led by the consul Appius Claudius Caudex, he withdrew to Syracuse. Pressed by the Roman forces, in 263 BC he concluded a treaty with Rome. By this agreement, he was to rule over the south-east of Sicily and the eastern coast as far as Tauromenium. This diplomatic shift marked a turning point in regional politics during the conflict. His alliance with Rome proved crucial for maintaining Syracuse's autonomy while other cities fell under Carthaginian control. The treaty established boundaries that would define Syracuse's territory for decades to come.
He kept up a powerful fleet for defensive purposes throughout his reign until his death shortly after the Battle of Cannae in 216 BC. He employed his famous kinsman Archimedes in the construction of engines that played so important a part during the siege of Syracuse by the Romans. These machines were designed to protect the city from naval attacks and ground assaults. Historical records indicate that these defensive innovations helped delay Roman conquest despite overwhelming odds. The collaboration between ruler and mathematician demonstrated how scientific knowledge could be applied to military strategy. Archimedes' work on floating bodies and mechanical devices became legendary through later accounts. His contributions transformed Syracuse into one of the most heavily fortified cities in the Mediterranean world.
According to a story told by Vitruvius, Hiero suspected he was being cheated by the goldsmith to whom he had supplied the gold to make a votive crown for a temple. He asked Archimedes to find out if all the gold had been used as agreed upon. Archimedes discovered the principle of displacement needed to measure the density of the crown while noticing the rise in water level when getting in a bath tub. In his excitement about the discovery, he dashed outside cheering and forgot to dress himself first. Vitruvius concludes this story by stating that Archimedes' method successfully detected the goldsmith's fraud. The smith had indeed taken some of the gold and substituted silver instead. This incident became known as the Eureka legend and illustrates early applications of physics to practical problems.
During the reign of Hieron II, various forms of architectural decoration were introduced in Sicily which are summarised as 'Hieronic architecture'. A picture of the prosperity of Syracuse during his rule is given in the sixteenth idyll of Theocritus. Contrary to some assumptions in scholarship, there is no evidence that these stylistic innovations were the result of a central programme on Hieron's part to legitimise his rule. Anna-Lena Krüger notes in her 2022 study that modern researchers have constructed this concept without direct proof from ancient sources. The Great altar of Syracuse was built under his direction and stands as one surviving example of the era's building projects. These structures reflected economic growth rather than political manipulation according to current historical analysis. Local craftsmen adopted new styles independently while maintaining traditional elements alongside imported influences.
In the 16th century treatise The Prince Chapter 6, Machiavelli cites Hiero as an exceptionally virtuous man and a rare example of someone who rose to princely power from previously being a private individual. He compares him to Moses, Cyrus, Theseus, and Romulus as models of successful leadership. This assessment highlights how Hiero managed to gain authority through merit rather than inheritance or force alone. His ability to maintain loyalty among allies while expanding territory made him stand out among contemporary rulers. Machiavelli used Hiero's story to illustrate principles of statecraft applicable to Renaissance Italy. The reference appears in discussions about acquiring principalities through personal capability versus fortune. Later historians have debated whether this portrayal accurately reflects Hiero's actual governance style or serves as idealized fiction for philosophical purposes.
