Amphiaraos,the hero from Argos that campaigned against Thebes,althought knew he would be killed

He was a hero from Argos. His father was called Oeklis and his mother Hypermnestra. He married the sister of Adrastos, Erifili, and acquired Alkmaion, Amphilochus, Eurydice and Iphianassa with her. He was an oracle, and so he knew that if he took part in the campaign against Thebes that Adrastos had prepared, he would be killed.

That's why he refused to take part. He was convinced by his wife Erifili, for they bribed her with the notorious necklace of Harmony. So Amphiaraus was forced to unite with the other leaders. But before he left, he had his son Alkmaion take an oath that he would avenge his death. When they arrived at Thebes, they besieged it and followed a terrible battle. Amphiaraos almost fell into the hands of the enemy. But Zeus intervened and suddenly split the earth open. The hero was drowned along with his chariot and thus avoided humiliation. In many cities of Greece he was worshiped as a hero and his famous temple in Oropos, Attica, Amphiaraeo is also well-known.
