I thought the final chapters were a bit on the daft side. Altogether, not a bad book, but nowhere near as good as Waverley.
Sir Walter Scott has a common theme. In Waverley, in particular, he celebrated the culture and national pride of the Highlanders, but appeared to think it was time for the English and Scots to forge forward together. In Ivanhoe the opposing peoples are the Saxons and Normans. Ivanhoe is a Saxon, Richard the Lionheart is a Norman. Ivanhoe's father, Cedric, wishes for the old days to come back, but finally accepts it is not possible.
Antisemitism is the other big theme in this book. Isaac of York is portrayed as a stereotypical money lender, but his daughter, Rebecca is very generous.
