every year the academy in paris would hold a big exhibition (art show) called the "salon de paris". in 1863 manet put a picture into the show called "lunch on the grass" ("le déjeuner sur l'herbe"). the judges at the salon refused to hang this work in the gallery because it showed a naked woman sitting on the grass with two men wearing clothes. if the painting had been about ancient greek mythology, this would not be a problem but these men were wearing ordinary suits, and the woman's dress and hat were lying on the grass. perhaps she was a prostitute. the judges said that the painting was indecent (very rude).
