Final answer:
The Pre-Raphaelites, an avant-garde art movement, emphasized the study of nature and medieval culture, rejecting the standards of the Royal Academy and its classical approaches.
Step-by-step explanation:
The careful study of nature and attention to details were among the Pre-Raphaelites’ ideals. Art historians have called the trailblazing Pre-Raphaelites the first avant-garde movement. The Pre-Raphaelites rejected the standards of the Royal Academy and its founder, Sir Joshua Reynolds, who stood for a traditional—even academic—approach to art. Pre-Raphaelites often married their art with themes from medieval culture.
