Take this at least, this last advice, my son:
Keep a stiff rein, and move but gently on:
The coursers of themselves will run too fast,
Your art must be to moderate their haste.
Tis on the living Envy feeds. She silent grows
When, after death, man's honor is his guard.
So I, when on the pyre consumed I lie,
Shall live, for all that's noblest will survive.
The raven once in snowy plumes was drest,
White as the whitest dove's unsullied breast,
Fair as the guardian of the Capitol,
Soft as the swan; a large and lovely fowl
His tongue, his prating tongue had changed him quite
To sooty blackness from the purest white.
