The enthroned figure, #1 in the numbered illustration, is usually taken to be Augustus, although in some interpretations, it could represent a later Roman ruler. Figure #3 is the most readily identifiable, having characteristics held by no other. The woman is Oikoumene - the personification of the inhabited world. This inhabited or civilized world is either that of the early Roman Empire, or more likely the Mediterranean world conquered by Alexander the Great. She wears upon her head a mural crown and veil. She is crowning figure #1 with the corona civica of oak leaves - used to commend someone for saving the life of a Roman citizen. In this grand scale depiction, however, it is given to figure #1 because he saved a multitude of Roman citizens.
