What you have to understand is that this book was written between probably 1833 and 1879 (year of death for the author, Jacob Abbott). The earliest printing I've found for it was a Harper & Brothers copy published in 1902 (at UCLA Young research library) The history is poor, in my opinion, even for the time; though I suppose there were still historians living at that time who believed King Arthur was a real, historical personage. It uses the pseudo-histories of Bede, Nennius, Geoffrey of Monmouth, as a basis, as if they were true history. It's an interesting read if you haven't yet been introduced to the subject; but understand that it is not true history. It contains a few facts that certainly are true; but they are mired within layers of folk stories and myth. The style will seem stilted and antiquary to the modern reader. It's only real value is for finding out what people believed English history to be before, say, 1850.
