Collins appears to be an expert on this topic. However I wish he would share more histroy with us. I understand that not much is known but the reader deserves more information. Unfortunately this is a 200 page bibliography which left me clueless on what happened in Spain during this period. This book should be titled "A List of Chronicles" I want my money back!
