deposits found in the silt of the Pactolus river (made famous by Midas), which ran through the Lydian capital, Sardis. Later coins, including some in the British Museum, were made from gold purified by heating with common salt to remove the silver. In Greek and Persian cultures the name of Croesus became a synonym for a wealthy man. He inherited great wealth from his father Alyattes, who had become associated with the Midas myth because Lydian precious metals came from the river Pactolus, in which King Midas supposedly washed away his ability to turn all he touched into gold. In reality, Alyattes' tax revenues may have been the real 'Midas touch' financing his and Croesus' conquests. Croesus' wealth remained proverbial beyond classical antiquity: in English, expressions such as "rich as Croesus" or "richer than Croesus" are used to indicate great wealth to this day. The earliest known such usage in English was John Gower's in Confessio amantis (1390): Original text: Modern spelling: Interview with Solon According to Herodotus, Croesus encountered the Greek sage Solon and showed him his enormous wealth. Croesus, secure in his own wealth and happiness, asked Solon who the happiest man in the world was, and was disappointed by Solon's response that three had been happier than Croesus: Tellus, who died fighting for his country, and the brothers Kleobis and Biton who died peacefully in their sleep after their mother prayed for their perfect happiness because they had demonstrated filial piety by drawing her to a festival in an oxcart themselves. Solon goes on to explain that Croesus cannot be the happiest man because the fickleness of fortune means that the happiness of a man's life cannot be judged until after his death. Sure enough, Croesus' hubristic happiness was reversed by the tragic deaths of his accidentally killed son and, according to Ctesias, his wife's suicide at the fall of Sardis, not to mention his defeat at the hands of the Persians. The interview is in the nature of a philosophical disquisition on the subject "Which man is happy?" It is legendary rather than historical. Thus, the "happiness" of Croesus is presented as a moralistic exemplum of the fickleness of Tyche, a theme that gathered strength from the fourth century, revealing its late date. The story was later retold and elaborated by Ausonius in The Masque of the Seven Sages, in the Suda (entry "Μᾶλλον ὁ Φρύξ,"
