The next stanza brings the next metaphor and a poem becomes a maze. It’s true that poems often have turns, are complex, and for some they can be confusing and hard to get through. Collins, when he says he wants to “drop a mouse into a poem . .” could be implying that poetry is best enjoyed and understood without a guide. Perhaps, the historical context and poet’s biography are not important in Collins’ poetry courses. Does the former poet laureate think of his students as mice lost in a maze? Does he take pleasure in watching them try to find their way out, or does he think that there is value in that struggle? Scientifically, a mouse in a maze is classic experiment, considered to be a wealth of knowledge, much like poetry.
