Yes, the story of King Midas and his golden touch is one of the most enduring Greek myths.
Midas, a Phrygian king (historically, Mita of the Mushki, ~8th c. BCE), hosted Silenus, Dionysus's tutor. Grateful, Dionysus granted Midas one wish. Midas chose: everything I touch turns to gold.
Dionysus instructs Midas to wash in the Pactolus River (modern Sart Çayı, Turkey). The gold-transfer power leaves his body, enriching the river's sands—explaining Lydia's historical electrum wealth.
Greed blinds; true value lies in sustenance, love, humanity. The myth warns against chrysophilia (gold-love) and the hubris of equating wealth with wellbeing.
Variants appear in Aristotle, Plato, Ovid, Nathaniel Hawthorne (A Wonder-Book), and countless modern adaptations.
