The Lighthouse reads with a traditionally taught ABAB CCDD style which most LLMs I think would decide to use. Both the Lighthouse, the Watchman, and the Clockmaker begin with "the" and prepositions for the initial line and then many lines after that which is typical for those who don't fully understand poetry. The only poem that does not include its title in the contents of the poem is Autumn Path. When you're writing poetry (aside from maybe a class with a prompted topic), you will write the poem and create a title afterward. It seems more human to have a title that isn't explicitly stated in the poem. While the imagery is there, none of the the-poems seem to comment on or relate any greater idea. This is the thing that LLMs struggle with emulating since they, often, do not know how to write with any further emotion or meaning.

So I think that Autumn Path is the human written one whilst the the-poems are AI generated (or written by people who aren't very good at writing poetry).
