If the question means the difference betweent two poems 'Landscape with the fall of Icarus' by Williams and 'Musee des Beaux Arts' by Auden the answer is :
The element which appears in Auden's poem but is not present in the poem by Williams is the reference to a ship which was sailing close by. The poet infers that the sailors on the ship probably saw 'something amazing' i.e. a man falling from the sky. Nevertheless, they did absolutely nothing, they did not try to help but continued to sail calmly as they had probably something more important to do. Auden uses the image of the ship which sails calmly without paying attention to this dramatic fact, to pinpoint the indifference of the people.
It seems to me that the research is not objective enough. The sources you used seem to give information only from the Russian side. Sources from a different point of view should be consulted; let's remember that history is written in most cases by the ones who are, or were, in charge. Maybe for Russian history Catherine the Great was really the best monarch that ever lived, but for countries that surrounded Russia she was not.
My suggestion si to determine the characteristics of a great monarch then, based on those characteristics, compare Catherine the Great with other monarchs. In that way your arguments will be solid and won't lack of credibility.
