Pausanias Description of Greece 4.33.7

[7]
  When the Electra is crossed, there is a spring called Achaia , and the ruins of a city Dorium. Homer states ¹ that the misfortune of Thamyris took place here in Dorium, because he said that he would overcome the Muses themselves in song. But Prodicus of Phocaea , if the epic called the Minyad ² is indeed his, says that Thamyris paid the penalty in Hades for his boast against the Muses. My view is that Thamyris lost his eyesight through disease, as happened later to Homer. Homer, however, continued making poetry all his life without giving way to his misfortune, while Thamyris forsook his art through stress of the trouble that afflicted him.
