That not an actor shall presume to squeak,
Unless he have a license for ‘t in Greek:
Nor devil in the puppet-play be allowed
To roar and spit fire, but to fright the crowd,
Unless some god or demon chance to have piques
Against an ancient family of Greeks;
That other men may tremble and take warning
How such a fatal progeny they’re born in;
For none but such for tragedy are fitted,
That have been ruined only to be pitied:
