Avantes was the first prehistoric greek tribe that settles in Euboea, mainly around two towns – Chalkis and Eretria – in the eras between 2100 – 1900 B.C. According to a myth they were named after nymph Ava.

They were warriors and had participated in the Trojan War under the command of Helephinor, their leader. In his epic poem ‘Iliad’ Homer refers to Avantes as follows: “Brave Avantes inhabitants of Euboea coming from Chalkis, Eretria as well as grape producing Istiea and Kirinthos by the sea and even high up from Dion, Karistos and Stira, all were commanded by Helephinor, fearless in battle, strong leader of theirs. Fast, long haired warriors carrying long spears, always willing to attack and beat the enemy.
