 Herodotus refers to a king of Tartessos, Arganthonios, presumably named for his wealth in silver.The people from Tartessos became important trading partners of the Phoenicians, whose presence in Iberia dates from the 8th century BC and who nearby built a harbor of their own, Gadir (, , present-day Cádiz).Several early sources, such as Aristotle, refer to Tartessos as a river.
