Casanova says "I went to Holland, to Belgium,
to Spain. In Oslo, I became seriously ill." But Norway's capital was called Christiania at the time; it did not adopt the name "Oslo" until 1925. And Belgium did not exist until 1830; that region would have been called the "Austrian Netherlands" or by the individual provinces of Brabant, Hainaut and Flanders.
