Observations on the History of Oil Painting

Historically, I think that the most important artists emerged in Renaissance times, people like Leonardo da Vinci, Rembrandt, Michelangelo, Titian, Raffaello Sanzio, and Botticelli. Later on, the worlds focus on oil painting spread to France and painters such as Claude Monet, Renoir, van Gogh, and Seurat. With these painters, new styles such as impressionism emerged. After thins point, oil painting focus spread more to across the globe, first to China, Japan and India, then to Africa and the Americas.
When I think about the history of oil painting, the cultures that are missing would be African paintings. This is probably because during the rest of the time when the world was painting, Africa was being colonized and taken over, I would think that the reason that African oil painting is so rare would be because people had more important things to do than paint.
I think that most of the oil painting in the world definitely took place all across Europe.
And most old and famous paintings that I know of are housed in museums across Europe like the Louvre. This is done probably to protect the paintings so that they don't get damaged or stolen because they are so rare and special. This also limits so many peoples access to them, today, to see any of these paintings, you need to go to France to the museum or have the Internet so see them over the computer. Its really sad hat this is so because not everyone can do these things or has access to these things.
Subject matter has also changed over time, back in the Renascence times, the subject was royalty and Gods, then it shifted into nature and landscape, then it shifted again to more modern and abstract ideas. This is most likely because of the worlds culture changes and changes in values among painters.
