SF and Juggling.

Dear group, I have just posted a message to a member who is also a Juggler.
I mentioned an SF book that I had read a few (15?) years ago.
There is a race of 4 handed (2 legged) peoples who juggle.
I think the juggling was not germain to the plot, and I vaguely remember a circus
surround.
Yours Guido

Sounds like Lord Valentine's Castle by Robert Silverberg.

Thanks, totally correct,
Guido.
