Please be advised that even though we use Dante's Divine Comedy as the theme for our company, we are not authorities on his life, his times, or his work. We have read his classic, and done some minor research into Dante's life, but that is the extent of our knowledge. As such, we regret that we cannot answer any scholastic questions that you might have in this area.
