Doch dieser Schwelle Zauber zu zerspalten

Bedarf ich eines Rattenzahns.

Noch eiaen Biss, so ist’s geschehn!

[But to break through the magic of this threshold

I need a rat's tooth. (He conjures up a rat.)

Another bite, and it is done!]

Er sieht in der geschwollen Ratte

Sein ganz naturlich Ebenbild.

[For in the bloated rat he sees

A living likness of himself]
