Who make old Romans like our English move,

Show Cato sparkish, or make Brutus love.

In a romance those errors are excused:

There 'tis enough that, reading, we're amused:

Rules too severe would there be useless found;

But the strict scene must have a juster bound;

Exact decorum we must always find.

If then you form some hero in your mind,

Be sure your image with itself agree;

For what he first appears, he still must be.
