Trophonius
A hero with an oracular cave at Lebadeia in Boeotia, where consultants descended underground for terrifying prophetic visions that left them unable to laugh for days.
The Legend of Trophonius
Trophonius was a legendary architect who, with his brother Agamedes, built Apollo's temple at Delphi and a treasury for King Hyrieus of Boeotia. After the brothers secretly robbed the treasury through a hidden passage, Agamedes was caught in a trap. Trophonius cut off his brother's head to prevent identification, then was swallowed by the earth at Lebadeia. The chasm became an oracle. Pausanias, the 2nd-century AD travel writer, described the consultation process in vivid detail: the seeker fasted for days, bathed in the river Hercyna, drank from the springs of Lethe (forgetfulness) and Mnemosyne (memory), then descended feet-first into a narrow underground chamber. Something in the darkness — visions, sounds, physical sensations — delivered the prophecy. Consultants emerged pale and shaken, temporarily unable to laugh.

Fun Fact
The phrase "he looks like he's been to Trophonius" was an ancient Greek idiom for someone who looked terrified or shell-shocked. Pausanias underwent the experience himself and confirmed it was genuinely frightening. Modern archaeologists have identified the cave system at Lebadeia and found it contains narrow passages that could induce claustrophobic panic — making Trophonius's oracle essentially the world's first haunted house attraction, 2,500 years before theme parks.
