Given the legendary status of Geryon, Gargoris and Habis, Arganthonios is the earliest documented monarch of the Iberian Peninsula.
[2][3] This idea of great age and length of reign may result from a succession of kings using the same name or title.
Hearing that the Medes were becoming a dominant force in the neighbourhood of the Phocaeans, he gave the latter money to build a defensive wall about their town.
Similar names (e.g. Argantoni) appear in inscriptions of the Roman period in or near former Tartessian territory.
[2] A name or title Argantoda(nos) is found on silver coinage in Northern Gaul and may have had a meaning akin to "treasurer".
