How does the portrayal of Nero's character in this painting compare to what you've read about Nero in "The Contest" and in the article?

The scene of people about to be burned before a large gathering and the painting's title are consistent with Nero's reputation as a harsh, ruthless tyrant, which the story and article also support. The scene in the painting closely relates to information in the article about Nero's persecution of Christians. Some people in the scene seem upset, but Nero is watching people about to be burned without any hint of being disturbed by what he sees. The tiger Nero holds by the leash might symbolize Nero's harshness and ferocity. The people about to be burned remind the audience of what it's like to be a victim of immense cruelty and injustice.

thats the plato answer!

They both seek of still paintings. They hold to the coloration.
