Context of "The Hymn to Intellectual Beauty"
After Mary Shelley's birth to their second child William in 1816 January, Shelley and Mary changed their plans for a trip to Italy and instead went to Lake Geneva, where Mary was inspired to write the now well known novel "Frankenstein". Here, Percy Shelley was inspired by the mountainsides and breathtaking scenery and as a result, he produced two of his most-appreciated poems: “Hymn to Intellectual Beauty” and "Mont Blanc". "The Hymn to Intellectual Beauty” was published in 1817 and talks about some "unseen power" that floats in and out of humans lives in the form of nature. This poem includes his personal experiences, as well as his religious views making it highly personal.
