Let us start by discussing murals. Specifically, I know nothing about murals. Let us suppose, though, that in a moment of masochism, I decide to write an eight page essay on them. I could stare at a blank screen feeling stupid, or, I could do a search for murals on Google. Out of an abundance of too much free time, I have actually just tried this. Quickly skimming the first three promising sources I find, I start making notes. They start something like this:
Earliest cave painting a form of mural. Used in religious ceremonies. Many murals in churches
Mexican Revolution. Murals used to challenge social oppression, justify revolution.
1930s America. African Americans use mural art to challenge racial bigotry.
A pattern is beginning to emerge here. All of the sources talk about murals as serving a political purpose. So, now I go from having a really broad topic (murals), to having a much narrower one (murals as political art). This of course allows me to do a new search in Google. I can take more notes from my additional sources, looking for more connections I can make between them. I also realize, in passing, that some of the sources are from Google Books, and are 300+ pages long. If someone can write 300 pages on the topic of murals, surely I can manage 8 with ease. I am learning and becoming more confident with every passing minute.
If you look up essay in a dictionary, you'll see it comes from the French word essayer, meaning "to try," to make an attempt." So, do some research, write down what you can, then post the prompt and your draft/notes here for more specific feedback.
