The deluge represents the story of the Great Flood, the passage from the Bible, when God drowned the whole Earth, saved only the occupants on Noah's Ark. The painting tells a story of desperation, agony, panic, and seeking a sanctuary. Leafless tree, nude figures, drowning people, the terror of humans' faces is creating a symbol of how life is leaving the earth, and it's a metaphor that humankind is powerless in the front of almighty.
The color of the water is not blue, but more white and grey, that compliments the tone of the painting perfectly. The overwhelming feeling of young and elder people dying in the greywater, the image of a man holding the drowned lifeless body of another, questions the decision of God.
The Deluge was created in 1508-9. It is located on the Sistine Chapel ceiling.
