This is a split portrait of the goddess Isis (or Auset) as she would have been seen in the different cultures that venerated her. On the left is the original Egyptian and Kushite portrayal or her, whereas on the right is the version the Greeks and Romans adopted after incorporating Egypt into their empires. In both cases, the goddess would have been represented in the image of her human disciples. It's a bit like how Jesus's appearance in art changes from Middle Eastern to European, African, etc. depending on the culture depicting him.Isis
