Who was Midas, a famous character from Greek myths?

The most famous King Midas is popularly remembered in Greek mythology for his ability to turn everything he touched into gold. This came to be called the golden touch, or the Midas touch.

One day, Dionysus found that his old schoolmaster and foster father, the satyr Silenus, was missing. The old satyr had been drinking wine and wandered away drunk, to be found by some Phrygian peasants who carried him to their king, Midas. Midas recognized him and treated him hospitably, entertaining him for ten days and nights with politeness, while Silenus delighted Midas and his friends with stories and songs. On the eleventh day, he took Silenus back to Dionysus in Lydia. Dionysus offered Midas his choice of whatever reward he wished for. Midas asked that whatever he might touch should be changed into gold.

Midas rejoiced in his new power, which he hastened to put to the test. He touched an oak twig and a stone; both turned to gold. Overjoyed, as soon as he got home, he touched every rose in the rose garden, and all became gold. He ordered the servants to set a feast on the table. Upon discovering how even the food and drink turned into gold in his hands, he regretted his wish and cursed it.
