The circus comes to town in Circle of Dead Girls.

Although there was no canvas tent (not invented for another twenty+ years), no exotic animals (the first circuses used pigs, horses and dogs) or trapeze artists, there were clowns.

The ancient Greeks used figures of fun, which were rustic fools. The English word for clown also meant rustic fool originally. These characters are plentiful in Shakespeare’s plays.

At the same time, the Italian Commedia del’arte used a number of stock characters that includes clown-like figures: Pierot and Harlequin.

Clowns have certain evolved since then.

The clown in the American circus is a direct outgrowth of Philip Astley, who restarted the circus in England in 1768. His circus was originally an equestrian show and clowns were used as the breaks between the trick riding.
