Nicolas Poussin was a French Painter from the seventeenth century who spent most of his life in Rome painting for private collectors. His style is defined by art historians as "classical baroque".
His paintings were classical because they sought clarity, rationality, and emotional restraint, but more importantly, because they often referred to themes of Ancient Greece and Rome. It was also Baroque because of the refinement and technical dexterity that he required to complete his works.
His was an inspiration to both Jacques-Louis David and Jean-Auguste-Dominique, who would define the Neoclassical style in France a century after.
American navy was withheld during the War of 1812 because the British navy would blow the US navy out of the water. Britain had more boats at the time than every other major naval power combined, and the US didn't stand a chance on the water.
Probably most likely desertification. all the animals eat all the grass which loosens the soil which in turn allows the wind to blow all the soil away and in time it is all replaced with desert.
