Æschylus went on gaining prizes for his tragedies, till 468, when, after being thirteen times first, he was excelled by another Athenian named Sophocles, and was so much vexed that he withdrew to the Greek colonies in Sicily.  It is not clear whether he ever came back to Athens for a time, but he certainly died in Sicily, and in an extraordinary way.  He was asleep on the sea-shore, when an eagle flew above him with a tortoise in its claws.  It is the custom of eagles to break the shells of these creatures by letting them fall on rocks from a great height.  The bird took Æschylus’ bald head for a stone, threw down the tortoise, broke his skull, and killed him!
