SPAIN / IBERIA (Pre-Roman Spain) Argantonio, King of Tartessos. (The golden man). According to the Greek historian Herodotus, King Arganthonios ruled Tartessia for 80 years (from about 625 BC to 545 BC) and lived to be 120 years old. This idea of great age and length of reign may result from a succession of kings using the same name or title. Herodotus says that Arganthonios warmly welcomed the first Greeks to reach Iberia, a ship carrying Phocaeans.
