A circus is commonly a traveling company of performers that may include acrobats, clowns, trained animals, trapeze acts, hoopers, tightrope walkers, jugglers, unicyclists and other stunt-oriented artists. The word also describes the performance that they give, which is usually a series of acts that are choreographed to music. A circus is held in an oval or circular arena with tiered seating around its edge; in the case of traveling circuses this location is most often a large tent called the big top.

Origin of the circus

In Ancient Rome the circus was a building for the exhibition of horse and chariot races, equestrian shows, staged battles, displays featuring trained animals, jugglers, and acrobats. The circus of Rome is thought to have been influenced by the Greeks, with chariot racing and the exhibition of animals as traditional attractions. The Roman circus consisted of tiers of seats running parallel with the sides of the course, and forming a crescent around one of the ends. The lower seats were reserved for persons of rank; there were also various state boxes, eg. for the giver of the games and his friends. In Ancient Rome the circus was the only public spectacle at which men and women were not separated. The Latin word circus comes from the Greek word kirkos meaning “circle or ring”.

The first circus in Rome was the Circus Maximus, in the valley between the Palatine and Aventine hills. Next in importance to the Circus Maximus in Rome was the Circus Flaminius, the Circus Neronis, from the notoriety which it obtained through the Circensian pleasures of Nero. A fourth, the Circus of Maxentius, was constructed by Maxentius; the ruins of this circus have enabled archaeologists to reconstruct the Roman circus.

Following the fall of Rome, Europe lacked a large and animal rich circus. Itinerant showmen traveled the fair grounds of Europe. Animal trainers and performers are thought to have exploited the nostalgia for the Roman circus, traveling between towns and performing at local fairs. Another possible link between the Roman and modern circus could have been bands of Gypsies who appeared in Europe in the 14th century and in Britain from the 15th century bringing with them circus skills and trained animals.fact: date=February 2008
