Deinomenid Tyranny 485-466 BC, AR Tetradrachm (16.85g).

Gelon also known as Gelo (Greek: Γέλων Gelon, gen.: Γέλωνος; died 478 BC), son of Deinomenes, was a Greek tyrant of the Sicilian cities Gela and Syracuse, Sicily, and first of the Deinomenid rulers.^[1][2]

Gelon was the son of Deinomenes. According to Herodotus, Gelon's ancestors came from the island of Telos in the Aegean Sea and were the founders of the city of Gela in southern Sicily.^[3] One of his later ancestors, Telines, was said to have reconciled his people after a period of civil strife through the divine rites of the Earth Goddesses; Herodotus infers that all of Telines' descendants, including Gelon, were priests of this cult.^[3]

Gelon's three brothers were Hieron, Thrasybulus and Polyzalos.^[4] Deinomenes consulted an oracle about the fates of his children, and was told that Gelon, Hieron and Thrasybulus were all destined to become tyrants.^{[citation needed]}
