It is very interesting to see how books were written at different times in history.  This book is from the 4th century and is organised in a way very different then modern books.  Some chapters are a paragraph or two just listing who was a bishop in some town since the 1st Christians were there.  Some are stories of martyrs.  Some are stories of heretics and their heresy.  Some relate back to other people's writings, as if it is something everyone would have read.
