Which literary device is used in line 11 of wingspaninson's poem?

" ... the Fields of Gazing Grain-"

irony

alliteration

simile

metonymy

metaphor

Well, it could either be metaphor for something (I'm not sure, I haven't read the poem) or 'alliteration', because G is repeated often. The rest of the options aren't possible, because there is nothing ironic here, nor is there a simile, or a metonymy.
