"Rhinocéros" is a play written by French playwright Eugène Ionesco in 1959. It is a key work of the theater of the absurd, exploring themes of conformity, culture, and the nature of humanity. The story unfolds in a small town where the inhabitants gradually transform into rhinoceroses, symbolizing the loss of individuality and the dangers of mass movements. The play features a central character, Berenger, who resists the transformation and struggles to maintain his humanity amidst the chaos. As his friends and loved ones succumb to the change, Berenger's fight against conformity highlights the importance of personal choice and the consequences of societal pressure.
