The poet Marcus Annaeus Lucan was 25 years old when he was forced to commit suicide. He was born in Cordova, Spain in November of 39 CE and slit his wrists in a Rome bathtub in April 65 CE. He was a brilliant Wunderkind, a Marvelous Boy like Mozart, and he composed perhaps the sickest document in the western literary canon: the Pharsalia, or Bellum Civile. The Civil War.
He was a peer and classmate of the emperor Nero, who ordered Lucan to kill himself. Again, Lucan was 25 years old at the time.
