The language I have learn'd these forty years, My native English, now I must forego: And now my tongue's use is to me no more Than an unstringed viol or a harp, Or like a cunning instrument cased up, Or, being open, put into his hands That knows no touch to tune the harmony: Within my mouth you have engaol'd my tongue, Doubly portcullis'd with my teeth and lips; And dull unfeeling barren ignorance Is made my gaoler to attend on me.
