An incredibly important element. The perspective on nature changed whereby it became less about the utility of nature and its functionality and more about its beauty. One of the first writers to encapsulate this idea was William Wordsworth. His Ode on Westminster Bridge is a great place to start. If you think about why someone would romanticise a bridge, and what he compares it to, you see a man looking at a man-made structure that represents utility. The making of bridges at the time was seen as monumentally important to the economy and a fantastic achievement of the industrial age. To compare this with emotional and natural notions was unheard of. No-one had seen this done in poetry before, yet, (and this is probably why it was such a successful piece of writing) as people walked past the bridge, they must have thought it was beautiful - in their own heads. Wordsworth was the first artist to put that in words.
