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.
