The rulers of this civilization were mythological. The first ruler of Tartessos was Geryon, a three-headed giant. He is also known for being the Tenth Labour of Heracles. The next ruler was his grandson, Norax, son of the Greek god Hermes and Geryon’s daughter, Erytheia. He later conquered the south of Sardinia and founded the city of Nora. After him came Gargoris, the son of the other daughter of Geryon, Evenor, and Poseidon. He was considered to be a good king for the Tartessian people and according to the myth he invented beekeeping. Gargoris had a son with his daughter and tried to hide him from the world by abandoning him. The child was raised by deers and became their leader. He taught them how to avoid the hunters, who got angrier and angrier to see their traps unleashed. One day, a hunter managed to trap the man and brought him to the king, Gargoris, who recognized him as his child and named him Habis. When his father died, he became the new king of Tartessos and made it flourish with new laws and a new social organization system.
