Can you give me an in depth description of how the different parts of these paintings evoke the end of the world aside from their darkness?
Besides the darkness, both also focus explicitly on destruction, including with the use of sometimes violent brushstrokes. In the case of Colman's painting, there is also a good amount of symbolism implying apocalyptic destruction. For instance, the falling winged figure is a representation of father time, one fundamental aspect of the world that is falling apart!
In the case of the Hamilton, while Hamilton is showing us a real event, the end of a city rather than the world, his interest is in the cyclical nature of civilizations.
Thanks for the answer, well said.
