What theatrical movement is characterized by man's trust in nature and the glorification of past civilizations?

The correct answer, Romanticism, is a theatrical movement that emerged in the late 18th century and flourished in the 19th century, characterized by its emphasis on emotion, individualism, and a deep appreciation for nature and the past. This movement often portrayed nature as a source of inspiration and truth, reflecting humanity's intrinsic connection to the natural world. Additionally, Romanticism glorified the achievements and ideals of past civilizations, celebrating their values and aesthetic choices as pathways to understanding and expressing the human experience.

This focus on the emotional response to nature and history distinguishes Romanticism from other movements. For instance, Realism aims to depict everyday life and society with a focus on authenticity, while Modernism embraces innovation and often critiques tradition. Symbolism employs metaphorical language and dream-like imagery to convey deeper truths, rather than the overt emotional and historical characteristics associated with Romanticism.

In summary, Romanticism's trust in nature and valorization of past civilizations encapsulate its core principles, making it the correct choice for this question.
