Although this is not your typical artwork that you usually see, this was made from the mind of a true artist. Francesco Goya took time to scrape and scratch this scene from what he could envision onto copperplate. Goya was known for his artwork being a part of Romanticism so it expressed past moments, insanity, nature and/or emotions. In an empty land/world sits a giant bare of clothing who is looking back at us to escape his own loneliness.
Now using the concept of Romanticism, this artwork has emotion in the sense you can relate to being all alone or even living in a small world. This could even be Goya trying to show his image of Goliath which falls under the category of past. Not really expressing nature but this can fit in the insanity category, maybe this is the mental state of how people sometimes feel on Earth which is big one moment just find out that the world is bigger.
