context: However, this was not always the case; in the early 20th century, once it became apparent that the "sport" was worked, pro wrestling was looked down on as a cheap entertainment for the uneducated working class — an attitude that still exists to varying degrees today. The French theorist Roland Barthes was among the first to propose that wrestling was worthy of deeper analysis, in his essay "The World of Wrestling" from his book Mythologies, first published in 1957. Barthes argued that it should be looked at not as a scamming of the ignorant, but as spectacle; a mode of theatric performance for a willing, if bloodthirsty, audience. Wrestling is described as performed art which demands an immediate reading of the juxtaposed meanings. The logical conclusion is given least importance over the theatrical performers of the wrestlers and the referee. According to Barthes, the function of a wrestler is not to win: it is to go exactly through the motions which are expected of them and to give the audience a theatrical spectacle. This work is considered a foundation of all later study.
