Outside of academic circles, The Harley 2253 Manuscript (also called the "Harley Lyrics"), is not widely known. However, it is one of the most important collections of works to have ever been written because of, mainly, its utilization of meta-narrative, which the Oxford English Dictionary defines as "an overarching account or interpretation of events and circumstances that provides a pattern or structure for people’s beliefs and gives meaning to their experiences."
Found in the British Library and dated approximately 1340, The Harley 2253 Manuscript is a collection of lyrics written in a number of languages - Middle English, Middle French, and Latin - and by a number of nameless authors (it has been postulated, however, that there were only three writers because of the handwriting on the original manuscript.) Also, the collection is about a wide variety of things, including religious subjects and non-religious subjects.
