In his text on Jonathan Swift from 1940, Johannes V. Jensen cited Don John's line
I am trusted with a muzzle and enfranchised with a clog; therefore I have decreed not to sing in my cage. If I had my mouth, I would bite; if I had my liberty, I would do my liking: in the meantime let me be that I am and seek not to alter me.
Jensen later explained that this was a reference to the censorship imposed after the German invasion of Denmark in 1940.[61]
