The Aeneid - pg. 310

Hercules heard him. Deep in his heart he quelled

A mighty groan, and let the vain tears flow.

At this the Olympian father addressed his son

In kindness:

"Every man's last day is fixed.

Lifetimes are brief, and not to be regained,

For all mankind. But by their deeds to make

Their fame last: that is labor for the brave.

Below the walls of Troy so many sons

Of gods went down, among them, yes, my child,

Sarpedon. Turnus, too, is called by fate.

He stands at the given limit of his years."
