My friend Karen alerted me to the novels of Anglea Thirkell, written some 80 years later, many (29) of which were set in the same fictional Barsetshire as the Trollope novels. I am starting with August Folly, written in 1936. What did I find on page 6? You guessed it: an Iceland reference:
Mr. Tebben was a Civil Servant during the week ... but in the evenings, and from Saturday to Monday, he gave himself entirely to the past, taking for his province the heroic age of Norway and Iceland ...
I think I'm going to like Angela Thirkell! I'm also partial to Thirkell since she described her books as "new wine in an old bottle."
