I think I have checked out every pub fireplace in NW................. THE EAGLES PENMACHNO cannot find who did the inscription.
I did have another go at the quote, best I could find........
This proverb is a good example of personification, then, because it ascribes human abilities to both Fear and Faith: both abstract and intangible concepts that are, obviously, not human. Fear is given the human ability to knock at a door; to do this, it must have both the intention to knock and the ability to do so—so it must have hands or some physical part with which it can knock. Faith is given the human ability to answer the door; to do this, it must have both the intention to open the door and the physical ability to do so. Again, then, it must have some body part with which it is capable of opening a door.
Ultimately, the proverb means that, when we have faith, we will have no need to fear. However, it uses two examples of personification in order to convey this idea
