If circus skills are not already considered an art, then they certainly should be. There is just as much skill in discipline in certain circus acts, such as trapeze, as there is in dance- which is considered a performance art.
    According to a Wikipedia article, “Contemporary circus combines traditional circus skills and theatrical techniques to convey a story or theme. Compared with the traditional circus, the contemporary genre of circus tends to focus more attention on the overall aesthetic impact, on character and story development, and on the use of lighting design, original music, and costume design to convey thematic or narrative content.”
