B.H. Warmington , Carthage, hard, [1960], 26, However, none of the references to the date of Gades can be considered trustworthy, but an unexpected source provides us with some information which is probably to do with Tartessos.
This is the Old Testament, and the passages concerned are those which are translated in our versions "ships of Tarshish". Tarshish is taken by some (though not all) scholars to be the Hebrew form of the name, which would be almost identical in Phoenician, and which was Hellenized as Tartessos; there seems in fact to have been an alternative form Tarseia, which is somewhat closer to Tharshish. Some of these texts refer to the days of Hiram and Solomon; one of the best known states that Solomon had "ships of Tarshish", and that they came every three years bringing gold, silver, ivory and monkeys. Solomon's ships sailed from Ezion-geber (Eilath) down the Red Sea, and it is fairly clear from this and other texts that the phrase "ships of Tharshish" was a technical term meaning a kind of ship capable of making long voyages... Ezekiel, describing the wealth of Tyre and the presence there of merchants from all nations, mentions silver, iron, tin, and lead, as traded by Tarshish. ... If Tarshish is really Tartessos, the references in Isaiah date the Phoenician voyages to before the beginning of the eight century.
