allusion

Where a poem makes reference to another poem or text. For example, the 14th line of //The Prelude// by [|William Wordsworth] 'The earth was all before me' alludes to one of the final lines of //Paradise Lost// by [|John Milton] 'The world was all before them'. //[|Paradise Lost]//, in turn, alludes to the story of Adam and Eve in //Genesis.// Allusion should not be confused with plagiarism.
