1.Here are some guidelines and instructions for over 4000 words dissertation. There are few questions that need to be answered:
*What is and how geometry becomes descriptive?
*How geometry has been used in paintings (relevant examples by choice)?
*What is the relationship between the concept of framing and painting?
*And lastly concluding WHY geometry has been used in paintings?
2. I have attached a 2000 word document which mentions the questions above that could be of help. I would like you to elaborate on those questions in-depth with included footnotes and bibliography with less internet sources please. I hope this helps, thanks.
