 The gold deposits in the river Pactolus that were the source of the proverbial wealth of Croesus (Lydia's last king) were said to have been left there when the legendary king Midas of Phrygia washed away the "Midas touch" in its waters.In Euripides' tragedy "The Bacchae", Dionysus, while he is maintaining his human disguise, declares his country to be Lydia.According to Herodotus, the Lydians were the first people to use gold and silver coins and the first to establish retail shops in permanent locations.
