Focus on After the Deluge (painting) and analyze the Subject.
After the Deluge depicts a scene from the story of Noah's Flood, in which Noah opens the window of the Ark to see that after forty days the rain has ended but the floodwaters have not yet subsided. Although his father's strict evangelical Christianity had instilled in Watts a strong dislike of organised religion, he had a deep knowledge of the Bible, and Noah and the Flood were both themes he regularly depicted throughout his career.Watts had a strong belief in the idea that modern society was prioritising wealth over social values, and that this attitude, which he described as "the hypocritical veiling of the daily sacrifice made to this deity", was leading to the decline of society. Hilary Underwood of the University of Surrey writes that Watts likely painted so many works on the theme of Noah as he saw modern parallels with the notion of the cleaning of a degenerate society while preserving those who still adhered to moral standards. Watts chose to depict the moment at which the sunlight became visible for the first time, after 40 days obscured by clouds.
And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month, were the tops of the mountains seen. And it came to pass at the end of forty days, that Noah opened the window of the ark which he had made.
