Hiero I of Syracuse

Hiero I (/ˈhaɪəroʊ/; also Hieron /ˈhaɪərɒn/; Ancient Greek: Ἱέρων) was the son of Deinomenes, the brother of Gelon and tyrant of Syracuse in Sicily, from 478 to 467 BC.

A bronze helmet (now in the British Museum[3]), with an inscription commemorating the event, was dedicated at Olympia.

[2] Hiero's reign was marked by the creation of what is believed to be the first secret police in Greek history, yet he was a liberal patron of literature and culture.

The poets Simonides, Pindar, Bacchylides, Aeschylus, and Epicharmus were active at his court, as well the philosopher Xenophanes.

He died at Catania/Aetna in 467 BC and was buried there, but his grave was later destroyed when the former inhabitants of Catania returned to the city.
