So I've been reading into animals who have changed history, i.e. the Monkey who killed Alexander I of Greece. And this one keeps popping up but I can only find it in books about dogs and no real history books. So I suspect its a myth, but it's always worth double checking.
Oh yeah, and if you know of any other animals who have changed history it'd be greatly appreciated.
Here's a link to one of the many dog books telling the tale. http://books.google.co.uk/books?id=ndYgity6bNwC&pg=PT416&dq=urian+dog+pope&hl=en&sa=X&ei=O9kqU-f6MIzdoAT68oKgDQ&ved=0CEgQ6AEwAQ#v=onepage&q=urian%20dog%20pope&f=false
No, that's not true. The reason the Pope decided to not permit the annulment (not divorce) of Henry VIII was that Henry VIII's wife, Catherine of Aragon, was the daughter of the King of Spain. At the time of Henry VIII's seeking of an annulment from the pope, Catherine's nephew, the Holy Roman Emperor Charles V, had just sacked Rome and the Pope was his prisoner. The Pope would never have dared to cross Charles V by granting Henry VIII's request.
