I am unable to determine the origin of the Colossus you are referring to. If you can provide more information such as the title of the picture, the author or other context information, I will try my best to help you find the source.
The Colossus often refers to the Colossus of Rhodes. It was a huge statue built in ancient Greece. It was a symbol of the city's power and prosperity. It was constructed to celebrate the city's victory over the ruler of Cyprus. The statue was said to be around 30 meters tall and was one of the Seven Wonders of the Ancient World.
The term 'colossus novel' is rather ambiguous. It could refer to a novel that is physically large, like an oversized or special edition. Or it could be a novel that has a colossal, or extremely significant, concept at its core. For example, it could be about a colossus - like figure in history or mythology, and the story could revolve around this figure's actions, their impact on the world around them, and the lessons that can be learned from their life. It could also be a novel that explores the idea of something being colossal in a more abstract sense, such as colossal love, colossal ambition, or colossal folly.
