London, a History: New Troy or Roman London?

I was a little confused when first reading this chapter. I thought that all of a sudden the author was backtracking from modern day London to primitive London; it dawned on me finally that the first chapter must have been more of an introduction, rather than an actual chapter.
Although the facts stated in this chapter were important to the development of the city of London, I felt it to be slightly boring. I’m not a fan of reading about history; but the author did us all a favor of summing it up in 2.5 pages.
