Pausanias Description of Greece 6.8.4

[4]
  The statue of Timanthes of Cleonae, who won the crown in the pancratium for men, was made by Myron of Athens , but Naucydes made that of Baucis of Troezen, who overthrew the men wrestlers. Timanthes, they say, met his end through the following cause. On retiring from athletics he continued to test his strength by drawing a great bow every day. His practice with the bow was interrupted during a period when he was away from home. On his return, finding that he was no longer able to bend the bow, he lit a fire and threw himself alive on to it. In my view all such deeds, whether they have already occurred among men or will take place hereafter, ought to be regarded as acts of madness rather than of courage.
