There are many different connection in this book to me. But im only going to tell you a few of them. The first one that stood out to me was that when Leonardo Vetra got murdered and had his eye bulged out of his head it reminded me of my uncle Joe who has only one eye because some one bulged it out of his own head and had to been rushed to the hostpital. So now we call him one eye Joe. Another connection in the book to me is that when langdon goes around Rome that each of the spots he goes too means earth air fire and water. and to me that is all i need to surive and when i wa younger me and my friends would always use those to survive the world we live in. Another one is the book is about different gods and how tey went around and all the clues related to omething of a god or even a goddess.but i only worship oon god but many people have there own belifes on wat they can and cannot worship and this reltes to me cause i alwasy worship my god. Another one is that the lumittie symbol langton got through the fax machine looks like wat me and my friend ds would make wen we would build are forts for air soft battles. Another connection i had made when i was reading the book is that he had to travel to these places to get an idea on how to write the book so he had to get to know rome and all the important citys and my parents go to rome every 3 years to get away from us kids. So those are some of my connections to the book i had hoped you enjoyed.
