According to Herodotus the Phocaeans were the first Greeks to make long sea-voyages, having discovered the coasts of the Adriatic, Tyrrhenia and Spain. Herodotus relates that they so impressed Arganthonios, king of Tartessus in Spain, that he invited them to settle there, and, when they declined, gave them a great sum of money to build a wall around their city.[7]
Their sea travel was extensive. To the south they probably conducted trade with the Greek colony of Naucratis in Egypt, which was the colony of their fellow Ionian city Miletus. To the north, they probably helped settle Amisos (Samsun) on the Black Sea, and Lampsacus at the north end of the Hellespont (now the Dardanelles). However, Phocaea's major colonies were to the west. These included Alalia in Corsica, Emporiae and Rhoda in Spain, and especially Massalia (Marseille) in France.[6]
Phocaea or Phokaia (Ancient Greek: Φώκαια, Phókaia; modern-day Foça in Turkey) was an ancient Ionian Greek city on the western coast of Anatolia. Greek colonists from Phocaea founded the colony of Massalia[1] (modern-day Marseille, in France) in 600 BC, Emporion (modern-day Empúries, in Catalonia, Spain) in 575 BC and Elea (modern-day Velia, in Campania, Italy) in 540 BC.
