Their language is considerably modernized, a process constantly going on where transcription is the means of transmission--not to mention that the actors would of course make many changes to the speech of their own time.

God, and angels, and Lucifer appear.

That God should here utter, I cannot say announce, the doctrine of the Trinity, may be defended on the ground that he does so in a soliloquy; but when we find afterwards that the same doctrine is one of the subjects upon which the boy Jesus converses with the doctors in the Temple, we cannot help remarking the strange anachronism.

Two remarkable lines in the said soliloquy are these: And all that ever shall have being It is closed in my mind.
The next scene is the _Fall of Man_, which is full of poetic feeling and expression both.
