At the corners of the central area, and at the corners of the outer area, there are two allegorical sculpture programs: four groups depicting Victorian industrial arts and sciences (agriculture, commerce, engineering and manufacturing), and four more groups representing Africa, the Americas, Asia and Europe at the four corners, each continent-group including several ethnographic figures and a large animal. (A camel for Africa, a bison for the Americas, an elephant for Asia and a bull for Europe.) Image and text from Wikipedia
