In classical mythology, a king who was granted one wish by the god Dionysus. Greedy for riches, Midas wished that everything he touched would turn to gold. He soon regretted his request. When he tried to eat, his food became inedible metal. When he embraced his daughter, she turned into a golden statue. On the instruction of Dionysus, he washed in a river and lost his touch of gold.
Note: A person who is very successful or easily acquires riches is sometimes said to have a “Midas touch.”
