Answer:
Notable motifs of Romantic art: subtlety, spirituality, inspiration (muse), the mind, meta-physicality, individualism, religion, nature, environment, imagination, childhood, innocence, nostalgia, and emotion.
Step-by-step explanation:
Romanticism put heavy emphasis on nature over man, and the splendor, beauty, glory, and power that nature holds. From soft flowery meadows to vicious lightning storms destroying the nature-defying creations of mankind, romanticist ideas stood in direct contrast to the ideals of the Industrial Revolution and concept of domination of nature by man popularized in the Enlightenment era. Certain older time periods were also glorified, specifically Greco-Roman and Medieval times. Such reliance on antiquity allowed for a sense of nostalgia to permeate romanticist works, which (sometimes literally) painted the past as a more simple and joyful time. Childhood was often portrayed with warm tones. Children, dressed in white, playing against stunning views of nature, venerating innocence and simple pleasure. Written works drew similar inspiration from the splendor of nature and anti-industrialism. In general, great emphasis were placed on mystical, spiritual, and/or religious themes, as well as of those of classical art or human individuality.
Of course, romanticism varied region by region; different cultures longed for different pasts. The style is chiefly about the emotions it may provoke in its audience.
