Like Midas, all he touches turns to gold. Midas, King of Phrygia, requested of the gods that everything he touched might be turned to gold. His request was granted, but as his food became gold the moment he touched it, he prayed the gods to take their favour back. He was then ordered to bathe in the Pactolus, and the river ever after rolled over golden sands.
