Pausanias, 6.9.6-9
“In the Olympiad before that one they say that Kleomêdês the Astupalaian killed the Epidaurian Hippos while boxing him. When he was charged by the referees with cheating and was deprived of the victory, he went out of his mind with grief and returned to Astupalaia.
There, he attacked a school there which held as many as sixty children and knocked down the pillar which supported the roof. After the roof fell on the children, the citizens threw stones at Kleomêdês and he fled into the Temple of Athena. Inside, he climbed into a chest and closed the lid over him.
The Astupalaians wore themselves out trying to open or break the chest. When they finally broke open the chest and did not find Kleomêdês there dead or alive, they send representatives to Delphi to ask what kind of thing had happened with Kleomêdês. The Pythia is said to have given the oracle that:
Kleomêdês the Astupalaian was the last of the heroes—
Honor him with sacrifices since he is no longer mortal.”
For this reason the Astupalaians have honored Kleomêdês as a hero since that time.
