Classic Poem

Old I am, yet can (I think)
Those that younger are out-drink;
When I dance no staff I take,
But a well-fill'd bottle shake:
He that doth in war delight,
Come, and with these arms let's fight;
Fill the cup, let loose a flood
Of the rich grape's luscious blood;
Old I am, and therefore may,
Like Silenus, drink and play.
