He covers the years from around 400 ad to 1000 ad, which is the period of time that the Church was at the height of it's power and glory. It is during these years that the doctrines of the RCC revealed their true nature. The nature of the church, while covered extensively, is not really the main focus of his work, which was the voyage of Magellan and the world he lived in, and he gives a quite detached and analytical portrait of simply what the world was like during that time. It was an attempt at a scholarly overview of the western world in that age, of which the Church was an integral part. Slightly dry reading, but very interesting and I highly recommend it.
You asked for one book, I gave you one, and even give you now HIS sources, so as I said, you can hash over the details with him if you choose. Personally, I am not going to waste further time with you. I say it is a waste of time because by challenging my assertions of the crimes by the RCC, and demanding my sources, you are either a)in denial and abjectly brainwashed to the point of being delusional, or b) aware that my accusations are true, and simply trying to make rhetorical points or trying to yank my chain. Given that you now say you have not denied my accusations, then I can only conclude that it be the latter. Whichever it may be, however, you have now made it onto the list of people with whom I consider discourse to be a waste of time.
As said above, He gets HIS facts from 75 footnoted sources (and I do think a number of them will probably qualify as "scholarly works on the history of the church"), including...

by challenging my assertions
I posted facts that proved them wrong. Which you then refused to read.
Here's your logical disconnect: You post your facts, on "legible to the masses" for one key example. Then you cite a book which even you don't claim supports your post.
He gets HIS facts
But what about the ones you posted?
I am impressed you read a book on the middle ages. I really am.
Here's all I'm saying. If you make factual assertions and I give contradictory information, then read it and respond, give your information.
I'm not saying the church is perfect, far from it. However, there is a great deal of virulent attacks that get repeated without challenge.
I'm challenging you to back up your specific assertions with more than just broad-brush condemnation. And I'm requesting you to back up your attacks with scholarship.
Believe it or not, I will even agree with you on some of them.
