The subtle distinction: Court Ball and Ball at Court: Zitat 1

From a letter written by Franz Joseph to Elisabeth:

Today is the great Court Ball, which, as always, will be a rather arduous pleasure.

The ball was very crowded, particularly large numbers of ladies, dancing as well, not many pretty ones among them, not hot at all. I was in my room by 12.
